Fwd: Testing OpenJDK under Windows 7 64, problem with Makefile

[Daniel López]

Well, I have been able to modify the Makefile so it does not depend on make
hanlding the ':', by transforming paths into linux style paths inside Make.
Then the problem is that Java itself seems not to like the Cygwin paths
(/cygdrive/c/...), maybe because it thinks it's running in windows?, so the
paths passed to Java have to be properly formatted as well.

So I have a working version of the Makefile, in Cygwin, and the question
would be if we want to investigate further how to get make to work with
that version or use the modified make-independent version. And in the
latter case, I can provide I diff of my changes so they can be revised and
tested. They are fairly simple changes but... :).

S!
