general: assume dot-starting file names are supported Now that we've dropped support for DJGPP, Windows 95/98/ME and MS-DOS, that should always the case. This change is basically a backport of Automake-NG commit 'v1.12-342-ge6af355'. * lib/am/texibuild.am: Just assume we can have directories whose name starts with a dot, i.e., that '${am__leading_dot}' expands to '.'. * automake.in (require_build_directory): Likewise. * m4/depend.m4 (AM_SET_DEPDIR): Likewise. Now $(DEPDIR) will be set unconditionally to '.deps'. * m4/init.m4 (AM_INIT_AUTOMAKE): Don't AC_REQUIRE the m4 macro 'AM_SET_LEADING_DOT' anymore. * m4/lead-dot.m4: Delete. * Makefile.am (dist_automake_ac_DATA): Remove it. * t/subobj11a.sh: Just assume $(DEPDIR) expands to '.deps'.
