Update.

2000-08-17  Greg McGary  <greg@mcgary.org>

	* Makeconfig (link-extra-libs-bounded): Strip `-bp' suffix
	from test program name when constructing suffix for $(LDLIBS-*).
	(bounded-thread-library): New variable.
	* crypt/Makefile
	[build-shared, build-static] (libcrypt-dep): Remove variable.
	($(addprefix $(objpfx),$(tests))): Consolidate individual dependencies.
	[build-bounded] ($(tests:%=$(objpfx)%-bp)): Add dependencies.
	* linuxthreads/Makefile (libpthread, librt): Remove variables.
	(librt-tests): Add variable.  (tests): Use it.
	[build-shared, build-static]
	($(addprefix $(objpfx),$(tests)), $(addprefix $(objpfx),$(librt-tests))):
	Consolidate individual dependencies.
	[build-bounded]
	($(tests:%=$(objpfx)%-bp), $(librt-tests:%=$(objpfx)%-bp)):
	Add dependencies.
	* math/Makefile (LDLIBS-*): Remove variables (they are redundant).
	[build-bounded] ($(tests:%=$(objpfx)%-bp)): Add dependencies.
	* misc/Makefile
	[build-bounded] ($(objpfx)tst-tsearch-bp): Add dependencies.
	* rt/Makefile
	[build-shared, build-static]
	($(addprefix $(objpfx),$(tests))): Consolidate individual dependencies.
