    Message : 2001-07-19 Tom Tromey <tromey@redhat.com> Alexandre Duret-Lutz <duret_g@epita.fr> Fix for ccnoco.test, subobj8.test: * m4/Makefile.am (m4data_DATA): Added auxdir.m4. * tests/Makefile.am (XFAIL_TESTS): Removed ccnoco.test, subobj8.test. * m4/minuso.m4 (AM_PROG_CC_C_O): Use absolute path to compile. Use AM_AUX_DIR_EXPAND. * lib/compile: Handle case where `-o' argument is the name of an executable, not an object file. * m4/auxdir.m4: New file, from... * m4/missing.m4: ... here. Moved AM_AUX_DIR_EXPAND. * automake.in (handle_single_transform_list, lang_c_rewrite): Require compile using `require_config_file'.
