Did you actually try running make in Unix mode as suggested in the FAQ?

Think about what you're asking. If you come up with a general, complete
solution to the problem of unambiguously converting DOS to Unix paths, and
vice-versa, without any additional information than what is in the paths
(don't forget the little problem of drive letters), patent it. A lot of
people would be very interested in your solution.
