Sorry but we make no guarantees that directly using Windows APIs in a
cygwin program will work reliably.  If you've found something that
doesn't work then that is not a huge surprise and it is not something
that we're going to look into fixing.

If you are writing a Windows program maybe you should check out the
MinGW project at http://mingw.org/ .
