[Mesa3d-dev] [RFC] Cygwin: Enable mesa to be built for Cygwin -with-driver=dri -with-dri-driver=swrast

[Jon T. <jon...@dr...>]

Why do I think I want to be able to do this?

Currently, libGL is built for cygwin using --with-driver=xlib

I've written a GLX provider for the Xwin Xserver which uses the native WGL 
interface, so now indirect GLX can be accelerated.

So now I need a libGL which can make use of this, but the realglx code in the x11 
driver which implemented the indirect path has been disabled from building for 
a while (see commit f440b0d and [1])

I've no idea when it last worked, and even if I could get it working again, I 
don't really want to be using code I am the only user of :-)

I've done various build tests on linux, which seem to work correctly, but, 
even if this is the correct approach, this could probably use a review to ensure 
I haven't broken anything.
