 [ **]  The RPC code is not 64 bit clean.  This is getting slowly fixed
        but expect incompatible changes on 64 bit platforms like Alpha.
 
+[ **]  If a DSO is using implicitly libpthread and the application itself
+       does not there is a name lookup problem.  E.g., the function fork()
+       will be found in the libc.so instead of libpthread since the thread
+       library is behind the libc.  To correct this problem it must *not*
+       be relied on the currently still enabled handling of weak symbols
+       in the dynamic linker.  Instead explicit tests for the availability
+       of the libpthread version are needed.  [PR libc/2325]

 [  *]  The precision of the `sinhl' and/or `asinhl' function do not seem
        to be the best.

 [  *]  The libm-ieee `scalb' function gives wrong results for
        non-integral second parameters.
 
-[  *]  Collation symbol and equivalence class handling in regex are not
-       yet 100% correct.
-       - [. .] at end of a range does not work
-       - [. .] and [= =] do not handle collating symbols (where a symbol
-         stands for multiple character) and multibyte character in
-         general not correctly.
+[  *]  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.
 
-       This is *extremely* hard to fix since regex has to be rewritten
-       completely.
+[  *]  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.
