Re: stat() vs cygwin

One motivation for keeping it working on Cygwin, is that in some
environments it is not allowed to install native Windows apps but
they allow the use of the Cygwin environment. Of course if it takes
too many resources to support, then dropping support would be an
option. I would check this for you, but I am in the middle of moving
and my Windows/Cygwin box is not available right now.

Cheers,
Ken
