Makefile.am: Remove OPTIMIZE_CXXFLAGS, WARN_CXXFLAGS, CONFIG_CXXFLAGS from here, and move to...
2000-10-06 Benjamin Kosnik <bkoz@purist.soma.redhat.com> * src/Makefile.am: Remove OPTIMIZE_CXXFLAGS, WARN_CXXFLAGS, CONFIG_CXXFLAGS from here, and move to... * src/Makefile.in: Regenerate. * Makefile.am: ... here. Clean. (OPTIMIZE_CXXFLAGS): Move up Makefile hierarchy to here. (WARN_CXXFLAGS): Same. (CONFIG_CXXFLAGS): Same. * Makefile.in: Regenerate. * libsupc++/Makefile.am: Use top-level OPTIMIZE_CXXFLAGS, WARN_CXXFLAGS, CONFIG_CXXFLAGS as part of local AM_CXXFLAGS. * libsupc++/Makefile.in: Regenerate. Change math to libmath. * math: Move to libmath, delete. * libmath: New directory. * libmath/*: Populate. * src/Makefile.am (LIBMATH_INCLUDES): Change to libmath. (libstdc___la_LIBADD): Same. * src/Makefile.in: Regenerate. * configure.in: Add AC_OUTPUT for libmath/Makefile. * configure: Regenerate. * Makefile.am (SUBDIRS): Add libmath. * Makefile.in: Regenerate. * README (file): Change name.
