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.
