And what happened? Were you able to get your makefile to work?

I said "without any additional information" because you couched your
requirement in a general way. The solution you're suggesting requires that
a user install Cygwin and create a mount table that maps DOS to Unix paths.

I suspect this is a solution of limited appeal to most developers of
Windows applications, including Sun.

It would be great if Sun or someone else ports javac to Cygwin, but at the
moment javac is a native Windows application and that was the situation I
addressed in my original response to you.
