	[BZ #5222]
	* elf/dl-load.c (_dl_rtld_di_serinfo): Correct handling of short
	path elements in counting mode.

2007-07-11  Jakub Jelinek  <jakub@redhat.com>

	[BZ #4776]
	* elf/dl-load.c (_dl_rtld_di_serinfo): Output / in LD_LIBRARY_PATH,
	RPATH etc. as "/" rather than "", don't segfault on empty paths,
	instead output ".".
	* dlfcn/Makefile (distribute): Add glreflib3.c.
	(module-names): Add glreflib3.
	($(objpfx)tst-dlinfo.out): Depend on glreflib3.so rather than
	glreflib1.so.
	(LDFLAGS_glreflib3.so): New.
	* dlfcn/tst-dlinfo.c (do_test): Load glreflib3.so instead of
	glreflib1.so.
	* dlfcn/glreflib3.c: New file.
