Ulrich Drepper 2f7f7bc658 Update. 
2003-06-16  Thorsten Kukuk  <kukuk@suse.de>

	* include/libc-symbols.h: Add static_link_warning macro.
	* grp/initgroups.c: Print linker warning if this function
	is called in a static linked binary.
	* nss/getXXbyYY.c: Likewise.
	* nss/getXXbyYY_r.c: Likewise.
	* nss/getXXent.c: Likewise.
	* nss/getXXent_r.c: Likewise.
	* sysdeps/posix/getaddrinfo.c: Likewise.

2003-06-16  Bruno Haible  <bruno@clisp.org>

	* iconvdata/gconv-modules (ISO-8859-15): Add aliases ISO_8859-15,
	LATIN-9.
	(ISO-8859-16): Add aliases ISO_8859-16:2001, ISO_8859-16.
	(IBM1047): Add alias IBM-1047.
	(GBK): Add aliases MS936, WINDOWS-936.

2003-06-16  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/unix/sysv/linux/xstatconv.c (__xstat_conv): Define even if
	defined __ASSUME_STAT64_SYSCALL && defined XSTAT_IS_XSTAT64.
	(__xstat64_conv): Change xstat_conv to __xstat_conv.
