glibc/sysdeps/unix/sysv/linux/ulimit.c
Ulrich Drepper 61423e13e5 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.
