[Patch 1/3] Small DOS issues

[Tim Van Holder]

Not sure if the first patch is acceptable; if not; it'll
just stay local to the DJGPP package.

2002-03-03  Tim Van Holder  <address@hidden>

        * lib/autoconf/general.m4: Work around a DJGPP issue when
        loading the cache file.
        * lib/m4sugar/m4sh.m4: Use the canonical test for absolute
        paths.
