Correct on all points.

For now, but this is not supported, and there are no guarantees as to
how long it will remain available.

An alternative may be for you to compile freeglut for WGL and use that
instead locally.  If you don't have libGL-devel (Mesa) installed, this
will be straightforward; if you do, you'll need to work
around /usr/include/GL.  I don't anticipate supporting this
configuration within the distro, but it should work for your own
purposes.  The attached .cygport should get you started.

The alternative is to build your application for native Windows, using
the mingw64-*-gcc compilers available in the distro and
mingw64-*-freeglut packages available in Cygwin Ports.
