Subject: * Makerules (check-abi) [$(enable-check-abi) = warn]:

	Ignore exit status from diff.
	* configure.in (enable_check_abi): Document possible value "warn".
	Change default to no for now.
	* configure: Regenerated.

	* sysdeps/unix/Makefile ($(objpfx)stub-syscalls.c): Emit stub_warning
	macro calls and a #include <stub-tag.h> at the end.
	* Makerules ($(objpfx)stubs): Tweak sed commands.

	* sysdeps/unix/sysv/linux/syscalls.list: Use - rather than EXTRA in
	caller column for *xattr syscalls, since they are in sysdeps/generic.

	* sysdeps/unix/sysv/linux/i386/setfsuid.c: setfsgid -> setfsuid
	* sysdeps/unix/sysv/linux/i386/setfsgid.c: setfsuid -> setfsgid

2003-03-26  Roland McGrath  <roland@redhat.com>

	* Makerules (check-abi-config): Use /thread instead of /tls when
	use-thread and not just use-tls is set.

	* Makerules (update-abi): Put quotes around $(update-abi-config).

	* elf/Makefile (check-abi): Depend on check-abi-ld.
	(update-abi): Depend on update-abi-ld.
