No, this is a different problem: $realpath and $abspath are broken on
Windows in Make 3.81, except in the Cygwin port with Posix file names
(that start with a slash).  (It cannot be the same problem, since
$abspath takes a single file name, not a list of directories, so the
significance of a colon as path separator is not an issue here.)

The next version will hopefully have this fixed.  If you must have
$abspath now, try the patch here:
