2004-03-18 Jakub Jelinek <jakub@redhat.com> * sysdeps/generic/dl-cache.c (_dl_load_cache_lookup): Remove hwcap variable and weak_extern for _dl_hwcap. (_DL_HWCAP_TLS_MASK): Define. (HWCAP_CHECK): Fix checking of non-platform hwcap bits. Use lib->osversion instead of cache_new->libs[middle].osversion. * stdio-common/asprintf.c: Remove USE_IN_LIBIO conditionals. * stdio-common/dprintf.c: Likewise. * stdio-common/fprintf.c: Likewise. * stdio-common/getline.c: Likewise. * stdio-common/getw.c: Likewise. * stdio-common/perror.c: Likewise. * stdio-common/printf-prs.c: Likewise. * stdio-common/printf.c: Likewise. * stdio-common/printf_size.c: Likewise. * stdio-common/psignal.c: Likewise. * stdio-common/putw.c: Likewise. * stdio-common/scanf.c: Likewise. * stdio-common/snprintf.c: Likewise. * stdio-common/sprintf.c: Likewise. * stdio-common/sscanf.c: Likewise. * stdio-common/tstgetln.c: Likewise. * stdio-common/vfprintf.c: Likewise. 2004-03-18 Paul Eggert <eggert@cs.ucla.edu> * posix/getopt.h (__GNUC_PREREQ) [!defined __THROW]: Define if not defined, fixing a typo (it used to be defined if __GNUC__ was not defined).
