    Hash : bb174399
    Message : Use `_dirstamp' when the file-system doesn't support `.dirstamp'. * m4/lead-dot.m4: New file. * m4/Makefile.am (dist_m4data_DATA): Add lead-dot.m4 * m4/init.m4 (AM_INIT_AUTOMAKE): Require AM_SET_LEADING_DOT.: * m4/depend.m4 (AM_SET_DEPDIR): Require AM_SET_LEADING_DOT. Define DEPDIR using am__leading_dot. * automake.in (require_build_directory): Define am__dirstamp, a new variable for the dirstamp basename, based on am__leading_dot. * tests/subobj6.test: Move all `test -f' into Makefiles, so we can use $(am__dirstamp). Reported by Richard Dawe.

    # There are a few dirty hacks below to avoid letting `AC_PROG_CC' be
    # written in clear, in which case automake, when reading aclocal.m4,
    # will think it sees a *use*, and therefore will trigger all it's
    # C support machinery.  Also note that it means that autoscan, seeing
    # CC etc. in the Makefile, will ask for an AC_PROG_CC use...
