glibc/include/string.h
Ulrich Drepper 4a691b0639 Update.
2004-05-26  Jakub Jelinek  <jakub@redhat.com>

	* include/string.h (mempcpy, stpcpy): Add libc_hidden_builtin_proto.
	* string/bits/string2.h (memset): Disable macro for GCC 3.0+.
	(__mempcpy): Use __builtin_mempcpy for GCC 3.4+.
	(strchr): For GCC 3.2+, only use __rawmemchr if second argument is
	constant '\0' and first argument is not constant.
	(__stpcpy): Use __builtin_stpcpy for GCC 3.4+.
	(strncpy): Remove #ifdef _USE_STRING_ARCH_mempcpy variant.
	For GCC 3.2+ use __builtin_strncpy.
	(strncat): For GCC 3.2+ use __builtin_strncat.
	(strcmp): For GCC 3.2+ use __builtin_strcmp if both arguments are
	constant.
	(strcspn, strspn, strpbrk): For GCC 3.2+, use builtin function
	if both arguments are constant.

	* nss/nss_files/files-hosts.c: Fix condition for looking up IPv4
	mapped addresses in gethostbyaddr.
