 Severity: [  *] to [***]
 

+[ **]  Closing shared objects in statically linked binaries most of the
+       times leads to crashes during the dlopen().  Hard to fix.

 
 

-[ **]  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 for ix86 does not work in the moment.
-
-[ **]  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 RPC code is not 64 bit clean.  This is getting slowly fixed
+       but expect incompatible changes on 64 bit platforms like Alpha.

 
 [  *]  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.

+[  *]  The libm-ieee `gamma' function gives wrong results (at least for
+       -0.5).
+
+[  *]  The libm-ieee `scalb' function gives wrong results for
+       non-integral second parameters.
+
+[  *]  Several (most?) collation specifications are broken.  The code which
+       is currently there is in most cases inherited from the originial
+       author (in case there is a LC_COLLATE specification in the locale
+       file) or is defined using the default (if iso14651_t1 is included).
+
+       In any case we are missing information to correct the specification.
+       If you find the specification for your language be faulty please
+       send a report with instruction on what to fix.  You don't have to
+       fix the specification yourself.
+
+       The way it finally should look like (if the generic specification
+       is not correct) can be seen in the sv_SE file.  Quite a few changes
+       on top of the generic specification can be made without duplication
+       of the whole LC_COLLATE description.
+
+[  *]  Some of the functions which also handled IPv6 are currently broken.
+       IPv6 and IPv4 lookups occasionally happen when not needed.  This
+       happens in getaddrinfo() and getnameinfo().  IPv4 handling of
+       these functions is OK though and there are patches available to fix
+       the IPv6 code as well.
