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.
