Update.

2000-04-02  Ulrich Drepper  <drepper@redhat.com>

	* elf/dl-fini.c (_dl_fini): Increment j counter after swapping in
	element at this position.

	* elf/Versions [ld.so] (GLIBC_2.2): Export _dl_load_lock.
	* elf/link.h (struct link_map): Add l_reldepsmax, l_reldepsact, and
	l_reldeps elements.
	* elf/dl-lookup.c (add_dependency): New function.
	(_dl_lookup_symbol): Use it whenever symbol was found in a global,
	dynamically loaded object.
	(_dl_lookup_symbol_skip): Likewise.
	(_dl_lookup_versioned_symbol): Likewise.
	(_dl_lookup_versioned_symbol_skip): Likewise.
	* elf/dl-open.c: Don't define _dl_load_lock here...
	* elf/rtld.c: ...but here...
	* elf/dl-support.c: ...and here.
	* elf/dl-close.c (_dl_close): Close also dependent objects introduce
	through relocation.
	* elf/dl-fini.c (_dl_fini): Also take dependencies introduced through
	relocations.
	* dlfcn/Makefile (glrefmain.out): Test is not expected to fail
	anymore.
	* dlfcn/glrefmain.c: Add one more debug message.

	* Makeconfig (preprocess-versions): Don't add $(CPPFLAGS) to compiler
	command line.
	* Makerules (sysd-versions): Use ( ) instead of { }.

	* elf/dl-load.c: Use __builtin_expect to signal that compiler should
	optimize for the non-debugging case.
	* elf/dl-lookup.c: Likewise.
	* sysdeps/generic/libc-start.c: Likewise.
