1999-10-20 Andreas Schwab <schwab@suse.de> * math/Makefile (libm-tests-generated): Remove libm-test.stmp. (generated): Add it here. (before-compile): Add libm-test.c. ($(addprefix $(objpfx), $(libm-tests-generated))): Depend on libm-test.stmp. ($(objpfx)libm-test.stmp): Use $(objpfx) instead of $(objdir)/math/.
