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.
