	* Makeconfig (CFLAGS): Prepend -std=gnu99.
	* Makerules (+make-deps): Use $(CFLAGS) only for .c sources.
	Remove superfluous rm command, whose @ plus make bugs hid
	all these commands from the make output.
2002-09-30  Roland McGrath  <roland@redhat.com>

	* elf/rtld-Rules: New file.
	* elf/Makefile ($(objpfx)librtld.map, $(objpfx)librtld.mk,
	$(objpfx)rtld-libc.a): New targets.
	(generated): Add them.
	(reloc-link): Remove -o $@ from the variable.
	($(objpfx)dl-allobjs.os): Add -o $@ after $(reloc-link).
	(distribute): Add rtld-Rules.
	(CPPFLAGS-.os): Define this instead of CFLAGS-.os.
	* Makerules ($(+sysdir_pfx)sysd-rules): Emit rules for rtld-% targets.
	(common-mostlyclean, common-clean): Clean up rtld-* files.
	* sysdeps/unix/make-syscalls.sh: Add rtld-*.os target name to rules.
