glibc/wcsmbs/wcwidth.h
Ulrich Drepper a1303dc8dc Update.
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>.
