+
+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

+[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:

+
+[A17] {RM} Believe it or not, stat and lstat (and fstat, and mknod)

+
+GROUP ( libc.so.6 ld.so.1 libc.a )
+
+
+{UD} The Linux ldconfig file probably generates a link libc.so ->
+libc.so.6 in /lib.  This is not correct.  There must not be such a
+link.  The linker script with the above contents is placed in
+/usr/lib which is enough for the linker.

+
+[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
+more freely it has another reason: user level programs now do not
+always use the same types like the kernel does.
+
+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
+results because of type conflicts.

+~~~~
+ * Method:
+ *   Bit by bit method using integer arithmetic. (Slow, but portable)
+ *   1. Normalization
+ *	Scale x to y in [1,4) with even powers of 2:
+ *	find an integer k such that  1 <= (y=x*2^(2k)) < 4, then
+ *		sqrt(x) = 2^k * sqrt(y)
+ *   2. Bit by bit computation
+ *	Let q  = sqrt(y) truncated to i bit after binary point (q = 1),
+ *	     i							 0
+ *                                     i+1         2
+ *	    s  = 2*q , and	y  =  2   * ( y - q  ).		(1)
+ *	     i      i            i                 i
+ *
+ *	To compute q    from q , one checks whether
+ *		    i+1       i
+ *
+ *			      -(i+1) 2
+ *			(q + 2      ) <= y.			(2)
+ *     			  i
+ *							      -(i+1)
+ *	If (2) is false, then q   = q ; otherwise q   = q  + 2      .
+ *		 	       i+1   i             i+1   i
+ *
+ *	With some algebric manipulation, it is not difficult to see
+ *	that (2) is equivalent to
+ *                             -(i+1)
+ *			s  +  2       <= y			(3)
+ *			 i                i
+ *
+ *	The advantage of (3) is that s  and y  can be computed by
+ *				      i      i
+ *	the following recurrence formula:
+ *	    if (3) is false
+ *
+ *	    s     =  s  ,	y    = y   ;			(4)
+ *	     i+1      i		 i+1    i
+ *
+ *	    otherwise,
+ *                         -i                     -(i+1)
+ *	    s	  =  s  + 2  ,  y    = y  -  s  - 2  		(5)
+ *           i+1      i          i+1    i     i
+ *
+ *	One may easily use induction to prove (4) and (5).
+ *	Note. Since the left hand side of (3) contain only i+2 bits,
+ *	      it does not necessary to do a full (53-bit) comparison
+ *	      in (3).
+ *   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".

+ *
+ *      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,

+ *	    | 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.

 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

 maintainers are encouraged to copy this distribution to their archives

+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.

+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.
