Hi, There was a change today in gnulib, that requires a small change in packages that use gnulib-tool --with-tests with --makefile-name. GNU m4 is one such package.
Currently, './bootstrap' fails like this: ... bootstrap: running: autoreconf --symlink --install tests/gnulib.mk:47: error: AM_CFLAGS must be set with '=' before using '+=' tests/Makefile.am:21: 'tests/gnulib.mk' included from here tests/gnulib.mk:48: error: AM_CXXFLAGS must be set with '=' before using '+=' tests/Makefile.am:21: 'tests/gnulib.mk' included from here autoreconf: error: automake failed with exit status: 1 The attached proposed patch fixes it.
