Update.
* inet/rcmd.c (rresvport_af): Avoid using invliad values. Wrap around in search if port IPPORT_RESERVED/2 has been test. 2002-02-20 Paolo Bonzini <bonzini@gnu.org> * posix/regcomp.c: Remove inclusions. * posix/regexec.c: Likewise. * posix/regex_internal.c: Likewise. * posix/regex_internal.h: Add inclusions here. * posix/regex.c: Only include sys/types.h before regex.h. Include regex_internal.h here. Include regex_internal.c before regcomp.c and regexec.c (might expose more opportunities to the C compiler). * posix/regcomp.c (parse_expression): Fix construct rejected by SGI CC. * posix/regex_internal.h [!_LIBC] (__mempcpy): Fix typo. [!_LIBC] (__wcrtomb): New definition. [!_LIBC]: Conditionalize enabling of I18N on HAVE_WCSCOLL and HAVE_LOCALE_H as well. 2003-02-20 Ulrich Drepper <drepper@redhat.com>
