[Patch] Some more DOS compatibility

[Tim Van Holder]

[This _might_ overlap some patches I previously sent it.]

* Some more support for DOS paths (i.e. backslashes as dirsep).

* The pathsep test was broken; it ran

PATH="foo"; command
         ^^^
The semicolon negated setting PATH.

* Use as_ln_s in config.status for CONFIG_LINKS.

        * acgeneral.m4: More support for DOS paths.  Fix pathsep
        test.  Add missing backslash.  Use $as_ln_s for making links.
