+[ **]  For GNU libc on Linux, there is still no solution for the UTMP
+       problem.
+       [Among others: PR libc/39]
+
+[ **]  There are problems with signal handling when using LinuxThreads.
+
+[ **]  The `cbrtl' function is inaccurate.  The algorithm used for `double'
+       and `float' is not usable for `long double'.
+
+[ **]  Not really a bug, but it could lead to such:
+       The RPC code is ugly ugly ugly.  It's more or less verbatim taken
+       from Sun's code and therefore mostly lacks complete prototypes and
+       (more important) the use of `const'.  It *definitely* needs to be
+       cleaned.
+
+[  *]  The precision of the `sinhl' and/or `asinhl' function do not seem
+       to be the best.
+
+[  *]  The syslog function should print to the console if the LOG_CONS
+       flag was given.
+       [PR libc/72]
+
+[  *]  On Linux, the <linux/posix_types.h> is not clean enough to satisfy
+       the C++ namespace rules.  Declaring `struct fd_set' also makes
+       `fd_set' available in the global namespace which conflicts with
+       the definition of `fd_set' in glibc.
+       [PR libc/79]
+
+[  *]  On Linux, there should be a way to prevent defining the symbol
+       NGROUPS_MAX in the <linux/limits.h> header file.  In glibc it
+       is defined in <posix1_lim.h> which must not make the other
+       symbols in <linux/limits.h> available.

+		Frequently Asked Question on GNU C Library
+
+As every FAQ this one also tries to answer questions the user might have
+when using the package.  Please make sure you read this before sending
+questions or bug reports to the maintainers.
+
+The GNU C Library is very complex.  The building process exploits the
+features available in tools generally available.  But many things can
+only be done using GNU tools.  Also the code is sometimes hard to
+understand because it has to be portable but on the other hand must be
+fast.  But you need not understand the details to use GNU C Library.
+This will only be necessary if you intend to contribute or change it.
+
+If you have any questions you think should be answered in this document,
+please let me know.

+[Q1]	``What systems does the GNU C Library run on?''
+
+[A1] {UD} This is difficult to answer.  The file `README' lists the
+architectures GNU libc is known to run *at some time*.  This does not
+mean that it still can be compiled and run on them in the moment.
+
+The systems glibc is known to work on in the moment and most probably
+in the future are:
+
+	*-*-gnu			GNU Hurd
+	i[3456]86-*-linux-gnu	Linux-2.0 on Intel
+	m68k-*-linux-gnu	Linux-2.0 on Motorola 680x0
+	alpha-*-linux-gnu	Linux-2.0 on DEC Alpha
+
+Other Linux platforms are also on the way to be supported but I need
+some success reports first.
+
+If you have a system not listed above (or in the `README' file) and
+you are really interested in porting it, contact
+
+	<bug-glibc@prep.ai.mit.edu>

+[Q2]	``What compiler do I need to build GNU libc?''
+
+[A2] {UD} It is (almost) impossible to compile GNU C Library using a
+different compiler than GNU CC.  A lot of extensions of GNU CC are
+used to increase the portability and speed.
+
+But this does not mean you have to use GNU CC for using the GNU C
+Library.  In fact you should be able to use the native C compiler
+because the success only depends on the binutils: the linker and
+archiver.
+
+The GNU CC is found like all other GNU packages on
+	ftp://prep.ai.mit.edu/pub/gnu
+or better one of the many mirror sites.
+
+You always should try to use the latest official release.  Older
+versions might not have all the features GNU libc could use.

+[Q3]	``When starting `make' I get only errors messages.
+	  What's wrong?''
+
+[A3] {UD} You definitely need GNU make to translate GNU libc.  No
+other make program has the needed functionality.
+
+Versions before 3.74 have bugs which prevent correct execution so you
+should upgrade to the latest version before starting the compilation.
+
+
+~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
+[Q4]	``After I changed configure.in I get `Autoconf version X.Y.
+	  or higher is required for this script'.  What can I do?''
+
+[A4] {UD} You have to get the specified autoconf version (or a later)
+from your favourite mirror of prep.ai.mit.edu.
+
+
+~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
+[Q5]	``Do I need a special linker or archiver?''
+
+[A5] {UD} If your native versions are not too buggy you can probably
+work with them.  But GNU libc works best with GNU binutils.
+
+On systems where the native linker does not support weak symbols you
+will not get a really ISO C compliant C library.  Generally speaking
+you should use the GNU binutils if they provide at least the same
+functionality as your system's tools.
+
+Always get the newest release of GNU binutils available.
+Older releases are known to have bugs that affect building the GNU C
+Library.

+[Q6]	``Do I need some more things to compile GNU C Library?''
+
+[A6] {UD} Yes, there are some more :-).
+
+* GNU gettext; the GNU libc is internationalized and partly localized.
+  For bringing the messages for the different languages in the needed
+  form the tools from the GNU gettext package are necessary.  See
+  ftp://prep.ai.mit.edu/pub/gnu or better any mirror site.
+
+* lots of diskspace (for i?86-linux this means, e.g., ~70MB).
+
+  You should avoid compiling on a NFS mounted device.  This is very
+  slow.
+
+* plenty of time (approx 1h for i?86-linux on i586@133 or 2.5h on
+  i486@66 or 4.5h on i486@33).  For Hurd systems times are much higher.
+
+  If you have some more measurements let me know.
+
+* When compiling for Linux:
+
+  + the header files of the Linux kernel must be available in the
+    search path of the CPP as <linux/*.h> and <asm/*.h>.
+
+* Some files depend on special tools.  E.g., files ending in .gperf
+  need a `gperf' program.  The GNU version (part of libg++) is known
+  to work while some vendor versions do not.
+
+  You should not need these tools unless you change the source files.

+[Q7]	``When I run `nm -u libc.so' on the produced library I still
+	  find unresolved symbols?  Can this be ok?''
+
+[A7] {UD} Yes, this is ok.  There can be several kinds of unresolved
+symbols:
+
+* magic symbols automatically generated by the linker.  Names are
+  often like __start_* and __stop_*
+
+* symbols starting with _dl_* come from the dynamic linker
+
+* symbols resolved by using libgcc.a
+  (__udivdi3, __umoddi3, or similar)
+
+* weak symbols, which need not be resolved at all
+  (currently fabs among others; this gets resolved if the program
+   is linked against libm, too.)
+
+Generally, you should make sure you find a real program which produces
+errors while linking before deciding there is a problem.

+[Q8]	``Can I replace the libc on my Linux system with GNU libc?''
+
+[A8] {UD} You cannot replace any existing libc for Linux with GNU
+libc.  There are different versions of C libraries and you can run
+libcs with different major version independently.
+
+For Linux there are today two libc versions:
+	libc-4		old a.out libc
+	libc-5		current ELF libc
+
+GNU libc will have the major number 6 and therefore you can have this
+additionally installed.  For more information consult documentation for
+shared library handling.  The Makefiles of GNU libc will automatically
+generate the needed symbolic links which the linker will use.
+
+

+[Q9]	``I expect GNU libc to be 100% source code compatible with
+	  the old Linux based GNU libc.  Why isn't it like this?''
+
+[A9] {DMT,UD} Not every extension in Linux libc's history was well
+thought-out.  In fact it had a lot of problems with standards compliance
+and with cleanliness.  With the introduction of a new version number these
+errors now can be corrected.  Here is a list of the known source code
+incompatibilities:
+
+* _GNU_SOURCE: glibc does not automatically define _GNU_SOURCE.  Thus,
+  if a program depends on GNU extensions or some other non-standard
+  functionality, it is necessary to compile it with C compiler option
+  -D_GNU_SOURCE, or better, to put `#define _GNU_SOURCE' at the beginning
+  of your source files, before any C library header files are included.
+  This difference normally manifests itself in the form of missing
+  prototypes and/or data type definitions.  Thus, if you get such errors,
+  the first thing you should do is try defining _GNU_SOURCE and see if
+  that makes the problem go away.
+
+  For more information consult the file `NOTES' part of the GNU C
+  library sources.
+
+* reboot(): GNU libc sanitizes the interface of reboot() to be more
+  compatible with the interface used on other OSes.  In particular,
+  reboot() as implemented in glibc takes just one argument.  This argument
+  corresponds to the third argument of the Linux reboot system call.
+  That is, a call of the form reboot(a, b, c) needs to be changed into
+  reboot(c).
+     Beside this the header <sys/reboot.h> defines the needed constants
+  for the argument.  These RB_* constants should be used instead of the
+  cryptic magic numbers.
+
+* swapon(): the interface of this function didn't changed, but the
+  prototype is in a separate header file <sys/swap.h>.  For the additional
+  argument of swapon() you should use the SWAP_* constants from
+  <linux/swap.h>, which get defined when <sys/swap.h> is included.
+
+* errno: If a program uses variable "errno", then it _must_ include header
+  file <errno.h>.  The old libc often (erroneously) declared this variable
+  implicitly as a side-effect of including other libc header files.  glibc
+  is careful to avoid such namespace pollution, which, in turn, means that
+  you really need to include the header files that you depend on.  This
+  difference normally manifests itself in the form of the compiler
+  complaining about the references of the undeclared symbol "errno".
+
+* Linux-specific syscalls: All Linux system calls now have appropriate
+  library wrappers and corresponding declarations in various header files.
+  This is because the syscall() macro that was traditionally used to
+  work around missing syscall wrappers are inherently non-portable and
+  error-prone.  The following tables lists all the new syscall stubs,
+  the header-file declaring their interface and the system call name.
+
+       syscall name:	wrapper name:	declaring header file:
+       -------------	-------------	----------------------
+       bdflush		bdflush		<sys/kdaemon.h>
+       create_module	create_module	<sys/module.h>
+       delete_module	delete_module	<sys/module.h>
+       get_kernel_syms	get_kernel_syms	<sys/module.h>
+       init_module	init_module	<sys/module.h>
+       syslog		ksyslog_ctl	<sys/klog.h>
+
+* lpd: Older versions of lpd depend on a routine called _validuser().
+  The library does not provide this function, but instead provides

+which differs from what your system currently has.  It was extended to
+fulfill the needs of the next years when IPv6 is introduced.  So the
+record size is different, fields might have a different position and

+[Q13]	``How do I configure GNU libc so that the essential libraries
+	  like libc.so go into /lib and the other into /usr/lib?''
+
+[A13] {UD,AJ} Like all other GNU packages GNU libc is configured to
+use a base directory and install all files relative to this.  If you
+intend to really use GNU libc on your system this base directory is
+/usr.  I.e., you run
+	configure --prefix=/usr <other_options>
+
+Some systems like Linux have a filesystem standard which makes a
+difference between essential libraries and others.  Essential
+libraries are placed in /lib because this directory is required to be
+located on the same disk partition as /.  The /usr subtree might be
+found on another partition/disk.
+
+To install the essential libraries which come with GNU libc in /lib
+one must explicitly tell this (except on Linux, see below).  Autoconf
+has no option for this so you have to use the file where all user
+supplied additional information should go in: `configparms' (see the
+`INSTALL' file).  Therefore the `configparms' file should contain:
+
+slibdir=/lib
+sysconfdir=/etc
+
+The first line specifies the directory for the essential libraries,
+the second line the directory for file which are by tradition placed
+in a directory named /etc.
+
+No rule without an exception: If you configure for Linux with
+--prefix=/usr, then slibdir and sysconfdir will automatically be
+defined as stated above.

+[Q14]	``When linking with the new libc I get unresolved symbols

+	  libc anymore?''
+
+[A14] {UD} Remember the US restrictions of exporting cryptographic
+programs and source code.  Until this law gets abolished we cannot
+ship the cryptographic function together with the libc.
+
+But of course we provide the code and there is an very easy way to use
+this code.  First get the extra package.  People in the US way get it
+from the same place they got the GNU libc from.  People outside the US
+should get the code from ftp.uni-c.dk [129.142.6.74], or another
+archive site outside the USA.  The README explains how to install the
+sources.
+
+If you already have the crypt code on your system the reason for the
+failure is probably that you failed to link with -lcrypt.  The crypto
+functions are in a separate library to make it possible to export GNU
+libc binaries from the US.

+[Q15]	``What are these `add-ons'?''
+
+[A15] {UD} To avoid complications with export rules or external source
+code some optional parts of the libc are distributed as separate
+packages (e.g., the crypt package, see Q14).
+
+To ease the use as part of GNU libc the installer just has to unpack
+the package and tell the configuration script about these additional
+subdirectories using the --enable-add-ons option.  When you add the
+crypt add-on you just have to use
+
+	configure --enable-add-ons=crypt,XXX ...
+
+where XXX are possible other add-ons and ... means the rest of the
+normal option list.
+
+You can use add-ons also to overwrite some files in glibc.  The add-on
+system dependent subdirs are search first.  It is also possible to add
+banner files (use a file named `Banner') or create shared libraries.
+
+Using add-ons has the big advantage that the makefiles of the GNU libc
+can be used.  Only some few stub rules must be written to get
+everything running.  Even handling of architecture dependent
+compilation is provided.  The GNU libc's sysdeps/ directory shows how
+to use this feature.

+[Q16]	``When I use GNU libc on my Linux system by linking against
+	  to libc.so which comes with glibc all I get is a core dump.''
+
+[A16] {UD} It is not enough to simply link against the GNU libc
+library itself.  The GNU C library comes with its own dynamic linker
+which really conforms to the ELF API standard.  This dynamic linker
+must be used.
+
+Normally this is done by the compiler.  The gcc will use
+
+	-dynamic-linker /lib/ld-linux.so.1
+
+unless the user specifies her/himself a -dynamic-linker argument.  But
+this is not the correct name for the GNU dynamic linker.  The correct
+name is /lib/ld.so.1 which is the name specified in the SVr4 ABi.
+
+To change your environment to use GNU libc for compiling you need to
+change the `specs' file of your gcc.  This file is normally found at
+
+	/usr/lib/gcc-lib/<arch>/<version>/specs
+
+In this file you have to change a few things:
+
+- change `ld-linux.so.1' to `ld.so.1' (or to ld-linux.so.2, see below)
+
+- remove all expression `%{...:-lgmon}';  there is no libgmon in glibc
+
+
+Things are getting a bit more complicated if you have GNU libc
+installed in some other place than /usr, i.e., if you do not want to
+use it instead of the old libc.  In this case the needed startup files
+and libraries are not found in the regular places.  So the specs file
+must tell the compiler and linker exactly what to use.  Here is for
+example the gcc-2.7.2 specs file when GNU libc is installed at
+/usr:

+
+[A21] {UD,AJ} On Linux, the use of kernel headers is reduced to a very
+minimum.  Besides giving Linus the possibility to change the headers

+
+I.e., the libc abstracts the use of types.  E.g., the sigset_t type is
+in the kernel 32 or 64 bits wide.  In glibc it is 1024 bits wide, in
+preparation for future development.  The reasons are obvious: we don't
+want to have a new major release when the Linux kernel gets these
+functionality. Consult the headers for more information about the changes.
+
+Therefore you shouldn't include Linux kernel header files directly if
+glibc has defined a replacement. Otherwise you might get undefined

+Recommended Tools to Install the GNU C Library
+----------------------------------------------
+
+   We recommend installing the following GNU tools before attempting to
+build the GNU C library:
+
+   * `make' 3.75
+
+     You need the latest version of GNU `make'.  Modifying the GNU C
+     Library to work with other `make' programs would be so hard that we
+     recommend you port GNU `make' instead.  *Really.* We recommend
+     version GNU `make' version 3.75 or later.
+
+   * GCC 2.7.2.1
+
+     On most platforms, the GNU C library can only be compiled with the
+     GNU C compiler.  We recommend GCC version 2.7.2 or later; earlier
+     versions may have problems.
+
+   * `binutils' 2.7
+
+     Using the GNU `binutils' (assembler, linker, and related tools) is
+     preferable when possible, and they are required to build an ELF
+     shared C library.  We recommend `binutils' version 2.7 or later;
+     earlier versions are known to have problems or to not support all
+     architectures.
+
+Supported Configurations
+------------------------
+
+   The GNU C Library currently supports configurations that match the
+following patterns:
+
+     alpha-ANYTHING-linux
+     alpha-ANYTHING-linuxecoff
+     iX86-ANYTHING-gnu
+     iX86-ANYTHING-linux
+     m68k-ANYTHING-linux
+     mips-ANYTHING-linux
+     sparc-ANYTHING-linux
+     powerpc-ANYTHING-linux
+
+   Former versions of this library used to support the following
+configurations but the current status is unknown:
+
+     alpha-dec-osf1
+     iX86-ANYTHING-bsd4.3
+     iX86-ANYTHING-isc2.2
+     iX86-ANYTHING-isc3.N
+     iX86-ANYTHING-sco3.2
+     iX86-ANYTHING-sco3.2v4
+     iX86-ANYTHING-sysv
+     iX86-ANYTHING-sysv4
+     iX86-force_cpu386-none
+     iX86-sequent-bsd
+     i960-nindy960-none
+     m68k-hp-bsd4.3

+     mips-sgi-irix4.N
+     sparc-sun-solaris2.N
+     sparc-sun-sunos4.N
+
+   Each case of `iX86' can be `i386', `i486', `i586', or `i686'.  All
+of those configurations produce a library that can run on any of these
+processors.  The library will be optimized for the specified processor,
+but will not use instructions not available on all of them.
+
+   While no other configurations are supported, there are handy aliases
+for these few.  (These aliases work in other GNU software as well.)

+Open jobs for finishing GNU libc:
+---------------------------------
+Status: April 1997
+
+If you have time and talent to take over any of the jobs below please
+contact <bug-glibc@prep.ai.mit.edu>
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+[ 1] Port to new platforms or test current version on formerly supported
+     platforms.
+
+**** See http://www.gnu.org/software/libc/porting.html for more details.
+
+
+[ 2] Test compliance with standards.  If you have access to recent
+     standards (IEEE, ISO, ANSI, X/Open, ...) and/or test suites you
+     could do some checks as the goal is to be compliant with all
+     standards if they do not contradict each other.
+
+
+[ 3] The IMHO opinion most important task is to write a more complete
+     test suite.  We cannot get too many people working on this.  It is
+     not difficult to write a test, find a definition of the function
+     which I normally can provide, if necessary, and start writing tests
+     to test for compliance.  Beside this, take a look at the sources
+     and write tests which in total test as many paths of execution as
+     possible.
+
+
+[ 4] Write translations for the GNU libc message for the so far
+     unsupported languages.  GNU libc is fully internationalized and
+     users can immediately benefit from this.
+
+     Take a look at the matrix in
+	ftp://prep.ai.mit.edu/pub/gnu/ABOUT-NLS
+     for the current status (of course better use a mirror of prep).
+
+
+[ 5] Write wordexp() function; this is described in POSIX.2, the
+     header <wordexp.h> already exists.
+
+     Implementation idea: use some functions from bash.
+
+**** Somebody is working on this.  Help may or may not be appreciated.
+
+
+[ 6] Write `long double' versions of the math functions.  This should be
+     done in collaboration with the NetBSD and FreeBSD people.
+
+     The libm is in fact fdlibm (not the same as in Linux libc).
+
+**** Partly done.  But we need someone with numerical experiences for
+     the rest.
+
+
+[ 7] Several math functions have to be written:
+
+     - exp2
+
+     each with float, double, and long double arguments.
+
+     Beside this most of the complex math functions which are new in
+     ISO C 9X should be improved.  Writing some of them in assembler is
+     useful to exploit the parallelism which often is available.
+
+
+[ 8] If you enjoy assembler programming (as I do --drepper :-) you might
+     be interested in writing optimized versions for some functions.
+     Especially the string handling functions can be optimized a lot.
+
+     Take a look at
+
+	Faster String Functions
+	Henry Spencer, University of Toronto
+	Usenix Winter '92, pp. 419--428
+
+     or just ask.  Currently mostly i?86 and Alpha optimized versions
+     exist.  Please ask before working on this to avoid duplicate
+     work.
+
+
+[ 9] Write nftw() function.  Perhaps it might be good to reimplement the
+     ftw() function as well to share most of the code.
+
+**** Almost done!
+
+
+[10] Extend regex and/or rx to work with wide characters and complete
+     implementation of character class and collation class handling.
+
+     It is planed to do a complete rewrite.
+
+
+[11] Write access function for netmasks, bootparams, and automount
+     databases for nss_files and nss_db module.
+     The functions should be embedded in the nss scheme.  This is not
+     hard and not all services must be supported at once.
+
+
+[12] Rewrite utmp/wtmp functions to use database functions.  This is much
+     better than the normal flat file format.
+
+**** There are plans for a new approach to this problem.  Please contact
+     bug-glibc@prep.ai.mit.edu before starting to work.)
+
+
+[13] Several more or less small functions have to be written:
+
+     + tcgetid() and waitid()			from XPG4.2
+     + grantpt(), ptsname(), unlockpt()		from XPG4.2
+     + getdate()				from XPG4.2
+	*** Probably underway
+     + fmtmsg()					from SVID
+	*** Probably underway
+
+     More information are available on request.
+
+
+[14] We need to write a library for on-the-fly transformation of streams
+     of text.  In fact, this would be a recode-library (you know, GNU recode).
+     This is needed in several places in the GNU libc and I already have
+     rather concrete plans but so far no possibility to start this.
+
+
+[15] Cleaning up the header files.  Ideally, each header style should
+     follow the "good examples".  Each variable and function should have
+     a short description of the function and its parameters.  The prototypes
+     should always contain variable names which can help to identify their
+     meaning; better than
+
+		int foo __P ((int, int, int, int));
+
+     Blargh!

+ * Method:

+ * 	Since gamma(1+s)=s*gamma(s), for x in [0,8], we may
+ * 	reduce x to a number in [1.5,2.5] by
+ * 		lgamma(1+s) = log(s) + lgamma(s)
+ *	for example,

+ *			    = log(6.3*5.3) + lgamma(5.3)
+ *			    = log(6.3*5.3*4.3*3.3*2.3) + lgamma(2.3)
+ *   2. Polynomial approximation of lgamma around its

+ *		lgamma(x) = -1.214862905358496078218 + z^2*poly(z)
+ *	where
+ *		poly(z) is a 14 degree polynomial.
+ *   2. Rational approximation in the primary interval [2,3]
+ *	We use the following approximation:

+ *	with accuracy
+ *		|P/Q - (lgamma(x)-0.5s)| < 2**-61.71

+ *
+ *   4. For negative x, since (G is gamma function)
+ *		-x*G(-x)*G(x) = pi/sin(pi*x),
+ * 	we have
+ * 		G(x) = pi/(sin(pi*x)*(-x)*G(-x))
+ *	since G(-x) is positive, sign(G(x)) = sign(sin(pi*x)) for x<0
+ *	Hence, for x<0, signgam = sign(sin(pi*x)) and

+ *	One may easily use induction to prove (4) and (5).

+ *   3. Final rounding
+ *	After generating the 53 bits result, we compute one more bit.
+ *	Together with the remainder, we can decide whether the
+ *	result is exact, bigger than 1/2ulp, or less than 1/2ulp
+ *	(it will never equal to 1/2ulp).
+ *	The rounding mode can be detected by checking whether
+ *	huge + tiny is equal to huge, and whether huge - tiny is
+ *	equal to huge for some floating point number "huge" and "tiny".

+expm1	Returns exp(x)-1, the exponential of x minus 1
+~~~~~
+ * Method
+ *   1. Argument reduction:
+ *	Given x, find r and integer k such that
+ *
+ *               x = k*ln2 + r,  |r| <= 0.5*ln2 ~ 0.34658
+ *
+ *      Here a correction term c will be computed to compensate
+ *	the error in r when rounded to a floating-point number.
+ *
+ *   2. Approximating expm1(r) by a special rational function on
+ *	the interval [0,0.34658]:
+ *	Since
+ *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 - r^4/360 + ...
+ *	we define R1(r*r) by
+ *	    r*(exp(r)+1)/(exp(r)-1) = 2+ r^2/6 * R1(r*r)
+ *	That is,
+ *	    R1(r**2) = 6/r *((exp(r)+1)/(exp(r)-1) - 2/r)
+ *		     = 6/r * ( 1 + 2.0*(1/(exp(r)-1) - 1/r))
+ *		     = 1 - r^2/60 + r^4/2520 - r^6/100800 + ...
+ *      We use a special Reme algorithm on [0,0.347] to generate
+ * 	a polynomial of degree 5 in r*r to approximate R1. The
+ *	maximum error of this polynomial approximation is bounded
+ *	by 2**-61. In other words,
+ *	    R1(z) ~ 1.0 + Q1*z + Q2*z**2 + Q3*z**3 + Q4*z**4 + Q5*z**5
+ *	where 	Q1  =  -1.6666666666666567384E-2,
+ * 		Q2  =   3.9682539681370365873E-4,

+ *  	(where z=r*r, and the values of Q1 to Q5 are listed below)
+ *	with error bounded by

+ *	    | 1.0+Q1*z+...+Q5*z   -  R1(z) | <= 2
+ *	    |                              |
+ *
+ *	expm1(r) = exp(r)-1 is then computed by the following
+ * 	specific way which minimize the accumulation rounding error:
+ *			       2     3
+ *			      r     r    [ 3 - (R1 + R1*r/2)  ]
+ *	      expm1(r) = r + --- + --- * [--------------------]
+ *		              2     2    [ 6 - r*(3 - R1*r/2) ]
+ *
+ *	To compensate the error in the argument reduction, we use
+ *		expm1(r+c) = expm1(r) + c + expm1(r)*c
+ *			   ~ expm1(r) + c + r*c
+ *	Thus c+r*c will be added in as the correction terms for
+ *	expm1(r+c). Now rearrange the term to avoid optimization
+ * 	screw up:
+ *		        (      2                                    2 )
+ *		        ({  ( r    [ R1 -  (3 - R1*r/2) ]  )  }    r  )
+ *	 expm1(r+c)~r - ({r*(--- * [--------------------]-c)-c} - --- )
+ *	                ({  ( 2    [ 6 - r*(3 - R1*r/2) ]  )  }    2  )
+ *                      (                                             )
+ *
+ *		   = r - E
+ *   3. Scale back to obtain expm1(x):
+ *	From step 1, we have
+ *	   expm1(x) = either 2^k*[expm1(r)+1] - 1
+ *		    = or     2^k*[expm1(r) + (1-2^-k)]
+ *   4. Implementation notes:
+ *	(A). To save one multiplication, we scale the coefficient Qi
+ *	     to Qi*2^i, and replace z by (x^2)/2.
+ *	(B). To achieve maximum accuracy, we compute expm1(x) by
+ *	  (i)   if x < -56*ln2, return -1.0, (raise inexact if x!=inf)
+ *	  (ii)  if k=0, return r-E
+ *	  (iii) if k=-1, return 0.5*(r-E)-0.5
+ *        (iv)	if k=1 if r < -0.25, return 2*((r+0.5)- E)
+ *	       	       else	     return  1.0+2.0*(r-E);
+ *	  (v)   if (k<-2||k>56) return 2^k(1-(E-r)) - 1 (or exp(x)-1)
+ *	  (vi)  if k <= 20, return 2^k((1-2^-k)-(E-r)), else
+ *	  (vii) return 2^k(1-((E+2^-k)-r))
+ *
+ * Special cases:
+ *	expm1(INF) is INF, expm1(NaN) is NaN;
+ *	expm1(-INF) is -1, and
+ *	for finite argument, only expm1(0)=0 is exact.

+ *
+ *      Note. If k=0, then f=x is exact. However, if k!=0, then f
+ *	may not be representable exactly. In that case, a correction

+ *	and add back the correction term c/u.
+ *	(Note: when x > 2**53, one can simply return log(x))
+ *

+ *	    |                             |
+ *	Note that 2s = f - s*f = f - hfsq + s*hfsq, where hfsq = f*f/2.
+ *	In order to guarantee error in log below 1ulp, we compute log

+Whether this is still true for this release is unknown.  Porting the
+library is not hard.  If you are interested in doing a port, please
+get on the mailing list by sending electronic mail to
+<bug-glibc-request@prep.ai.mit.edu>.
 
 The GNU C library now includes Michael Glad's Ultra Fast Crypt, which
 provides the Unix `crypt' function, plus some other entry points.
 Because of the United States export restriction on DES implementations,
 we are distributing this code separately from the rest of the C
 library.  There is an extra distribution tar file just for crypt; it is
-called `glibc-VERSION-crypt.tar.gz'.  You can just unpack the crypt
+called `glibc-crypt-VERSION.tar.gz'.  You can just unpack the crypt
 distribution along with the rest of the C library and build; you can
 also build the library without getting crypt.  Users outside the USA
-can get the crypt distribution via anonymous FTP from ftp.uni-c.dk
-[129.142.6.74], or another archive site outside the USA.  Archive
+can get the crypt distribution via anonymous FTP from ftp.ifi.uio.no
+[129.240.64.21], or another archive site outside the USA.  Archive
 maintainers are encouraged to copy this distribution to their archives
-outside the USA.  Please get it from ftp.uni-c.dk; transferring this
+outside the USA.  Please get it from ftp.ifi.uio.no; transferring this
 distribution from prep.ai.mit.edu (or any other site in the USA) to a
 site outside the USA is in violation of US export laws.
 
+Beside the separate crypt tar file there are some more add-ons which can be
+used together with GNU libc.  They are designed in a way to ease the
+installation by integrating them in the libc source tree.  Simply get the
+add-ons you need and use the --enable-add-ons option of the `configure'
+script to tell where the add-ons are found.  Please read the FAQ file for
+more details.

 See the file INSTALL to find out how to configure, build, install, and port
-the GNU C library.
+the GNU C library.  You might also consider reading the WWW pages for the
+GNU libc at http://www.gnu.org/software/libc/libc.html.
 
 The GNU C Library is completely documented by the Texinfo manual found
 in the `manual/' subdirectory.  The manual is still being updated and
 contains some known errors and omissions; we regret that we do not have
 the resources to work on the manual as much as we would like.  Please
-send comments on the manual to bug-glibc-manual@prep.ai.mit.edu, and
+send comments on the manual to <bug-glibc-manual@prep.ai.mit.edu>, and
 not to the library bug-reporting address.
 
 The file NOTES contains a description of the feature-test macros used
 in the GNU C library, explaining how you can tell the library what
 facilities you want it to make available.
 
-Send bug reports to bug-glibc@prep.ai.mit.edu.
+We prefer to get bug reports sent using the `glibcbug' shell script which
+is install together with the rest of the GNU libc to <bugs@gnu.ai.mit.edu>.
+Simply run this shell script and fill in the information.  Nevertheless
+you can still send bug reports to <bug-glibc@prep.ai.mit.edu> as normal
+electronic mails.
 
 The GNU C Library is free software.  See the file COPYING.LIB for copying
 conditions.

-The GNU C library now includes Michael Glad's Ultra Fast Crypt, which

-distributing this code separately from the rest of the C library.  There is
-an extra distribution tar file just for crypt; it is called
-`glibc-1.07-crypt.tar.gz'.  You can just unpack the crypt distribution
-along with the rest of the C library and build; you can also build the
-library without getting crypt.  Users outside the USA can get the crypt
-distribution via anonymous FTP from ftp.uni-c.dk [129.142.6.74], or another
-archive site outside the USA.  Archive maintainers are encouraged to copy
-this distribution to their archives outside the USA.  Please get it from
-ftp.uni-c.dk; transferring this distribution from prep.ai.mit.edu (or any
