Patch 1 of 4: Better DOS path support

[Tim Van Holder]

2001-02-10  Tim Van Holder  <address@hidden>

        * ylwrap: Support DOS-style absolute paths.  Don't use
        'ln -s' on DOSish systems.
        * tests/defs: Support DOS-style absolute paths.
        * tests/installsh.test: Support DOS-style absolute paths.
