Update.
* sysdeps/unix/sysv/linux/ulimit.c (__ulimit): Handle overflow in UL_SETFSIZE computations better. * string/Versions: Export __strsep for GLIBC_2.2.5. * string/bits/string2.h: Define all __STRING_INLINE functions if _FORCE_INLINES is defined. Use int instead of char of parameter types. (__strsep): Don't use __strsep_g. Don't define it. (__strsep_1c, __strsep_2c, __strsep_3c): Optimize. * sysdeps/i386/i486/string.h (__strcpy_a_small): Renamed from __strcpy_small. (__stpcpy_a_small): Renamed from __stpcpy_small. (__strcspn_c1): Don't define if _FORCE_INLINES. (__strspn_c1): Likewise. 2001-09-22 Ben Collins <bcollins@debian.org> * sysdeps/sparc/bits/sigaction.h: Define SA_RESTART and friends when _UNIX98_SOURCE is defined too. Matches generic/bits/sigaction.h. * sysdeps/ia64/bits/sigaction.h: Likewise. * sysdeps/s390/s390-64/bits/sigaction.h: Likewise. 2001-09-24 Andrew Haley <aph@cambridge.redhat.com> * sysdeps/unix/sysv/linux/sh/Makefile (sysdep_headers): Add sys/io.h. 2001-09-24 Jakub Jelinek <jakub@redhat.com> * elf/dl-open.c (dl_open_worker): Update l_scope_max. 2001-09-24 Ulrich Drepper <drepper@redhat.com>
