Re: Strange behaviour of vpath with dos paths

["Johan Bezem" <jbezem at csksoftware dot com>]

Hi,

OK, so I think I fixed the problem with the vpath directive, I fixed
another related problem on the way (the GPATH variable shows the same
symptoms), I tested both fixes on my machine, and wrote a ChangeLog
entry.
Now, I want to contribute these fixes into the development chain for
CygWin make.
The GNU make project (http://savannah.gnu.org/projects/make) does not
contain the CygWin enhancements in its main development tree, but in
order to provide a valid diff, I'd have to incorporate my changes into
the latest CVS version and perform a diff, rather than using the sources
from the latest CygWin distribution.
I checked the CVS repository sources.redhat.com, but it seems to contain
only the core of the CygWin DLL's sources.
So, my question: Where can I find the repository of the CygWin make
package? Or otherwise, how to proceed from here?

Thanks,

Johan Bezem
