+make sure that bugs you report are not listed here.  If you can fix one
+of these bugs/limitations I'll certainly be glad to receive a patch.

+Another source of information about bugs is the problem data base of the
+GNU project.  There is an easy to use WWW interface is available at
+
+	http://www-gnats.gnu.ai.mit.edu:8080/cgi-bin/wwwgnats.pl
+
+I would appreciate it very much if you could verify the problem was not
+reported before by looking though the database.  To make the information
+in this data as useful as possible please report bugs always using the
+`glibcbug' shell script which gets installed with GNU libc.

+Severity: [  *] to [***]
+
+
+[ **]  For GNU libc on Linux, there is still no solution for the UTMP
+       problem.  Two people are working on a possible solution.
+       [Among others: PR libc/39]
+
+[ **]  There are problems with signal handling when using LinuxThreads.
+
+[ **]  The `cbrtl' function for ix86 does not work in the moment.
+
+[  *]  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.
+       [PR libc/140]
+
+[  *]  The localedef program should interpret only the required categories
+       addressed by `copy' statements.  This especially means that limited
+       character sets must not lead to errors if the LC_CTYPE category in
+       the locale addressed by `copy' is not really used.
+
+[  *]  Statically linking with libpthread leads to strange warnings
+       from the linker.  I don't know why this happen so far.

+@subsection Scanning the Content of a Directory
+
+A higher-level interface to the directory handling functions is the
+@code{scandir} function.  With its help one can select a subset of the
+entries in a directory, possibly sort them and get as the result a list
+of names.
+
+@deftypefun int scandir (const char *@var{dir}, struct dirent ***@var{namelist}, int (*@var{selector}) (struct dirent *), int (*@var{cmp}) (const void *, const void *))
+
+The @code{scandir} function scans the contents of the directory selected
+by @var{dir}.  The result in @var{namelist} is an array of pointers to
+structure of type @code{struct dirent} which describe all selected
+directory entries and which is allocated using @code{malloc}.  Instead
+of always getting all directory entries returned, the user supplied
+function @var{selector} can be used to decide which entries are in the
+result.  Only the entries for which @var{selector} returns a nonzero
+value are selected.
+
+Finally the entries in the @var{namelist} are sorted using the user
+supplied function @var{cmp}.  The arguments of the @var{cmp} function
+are of type @code{struct dirent **}.  I.e., one cannot directly use the
+@code{strcmp} or @code{strcoll} function; see the function
+@code{alphasort} below.
+
+The return value of the function gives the number of entries placed in
+@var{namelist}.  If it is @code{-1} an error occurred and the global
+variable @code{errno} contains more information on the error.
+@end deftypefun
+
+As said above the fourth argument to the @code{scandir} function must be
+a pointer to a sorting function.  For the convenience of the programmer
+the GNU C library contains an implementation of a function which is very
+helpful for this purpose.
+
+@deftypefun int alphasort (const void *@var{a}, const void *@var{b})
+The @code{alphasort} function behaves like the @code{strcmp} function
+(@pxref{String/Array Comparison}).  The difference is that the arguments
+are not string pointers but instead they are of type
+@code{struct dirent **}.
+
+Return value of is less than, equal to, or greater than zero depending
+on the order of the two entries @var{a} and @var{b}.

+@subsection Simple Program to List a Directory, Mark II
+
+Here is a revised version of the directory lister found above
+(@pxref{Simple Directory Lister}).  Using the @code{scandir} function we
+can avoid using the functions which directly work with the directory
+contents.  After the call the found entries are available for direct
+used.
+
+@smallexample
+@include dir2.c.texi
+@end smallexample
