2000-04-05 Cristian Gafton <gafton@redhat.com> * ctype/ctype.h (__isctype_l): Define even if not __OPTIMIZE__ because it is used in generic code. * wctype/wctrans.c: Define __ctype32_toupper and __ctype32_tolower. * wcsmbs/wcwidth.h: Declare __ctype32_b. * intl/gettext.c: Include <locale.h>. * intl/ngettext.c: Likewise. 2000-04-05 Jakub Jelinek <jakub@redhat.com> * resolv/inet_ntop.c (inet_ntop4, inet_ntop6, inet_ntop): Use socklen_t type for size. * sysdeps/sparc/sparc32/dl-machine.h (RTLD_START): Rewrite for new init function interface. * sysdeps/sparc/sparc64/dl-machine.h (RTLD_START): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/setjmp.h: Don't include sys/ucontext.h. (__jmp_buf): Declare the whole type structure here, don't use ucontext. * iconv/skeleton.c (put16u): Fix typo. Reported by Bruno Haible <haible@ilog.fr>.
