glibc/sysdeps/generic/strtok_r.c
Ulrich Drepper ee600e3f76 Update.
2004-07-10  Ulrich Drepper  <drepper@redhat.com>

	* elf/ldconfig.c: Define PROCINFO_CLASS as static before including
	ldsodefs.h.
	* sysdeps/generic/ldsodefs.h: Only define PROCINFO_CLASS if it is not
	already defined.
	* sysdeps/i386/dl-procinfo.c: Define PROCINFO_CALLS only if not
	already defined.

	* elf/rtld.c (print_statistics): Mark with noinline attribute.
	* sysdeps/i386/dl-machine.h (elf_machine_rel): Mark with always_inline
	attribute.
	(elf_machine_rel_relative): Likewise.

	* include/string.h: Add libc_hidden_proto for __strtok_r and
	__strsep_g.
	* sysdeps/generic/strsep.c: Add libc_hidden_def.
	* sysdeps/generic/strtok_r.c: Likewise.
	* sysdeps/i386/strtok_r.S: Add alias for internal symbol.
	* sysdeps/i386/i686/strtok_r.S: Likewise.
	* sysdeps/x86_64/strtok_r.S: Likewise.

2004-07-09  Alexandre Oliva  <aoliva@redhat.com>

	* inet/getnetgrent_r.c (internal_setnetgrent): Make it hidden
	instead of internal-linkage, such that we can alias to it.
	(internal_endnetgrent, internal_getnetgrent_r): Likewise.
