Update.
2004-03-22 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/sparc/sparc32/getpagesize.c (__getpagesize): Avoid warning about writing into read-only memory. * string/Makefile (routines): Add xpg-strerror. * string/string.h (strerror_r): If __USE_XOPEN2K but not __USE_GNU, redirect strerror_r to __xpg_strerror_r. * string/Versions (libc): Add __xpg_strerror_r@@GLIBC_2.3.4. * sysdeps/generic/xpg-strerror.c: New file. * sysdeps/mach/xpg-strerror.c: New file.
