>Subject: [PATCH 2/3] Cygwin: Enable mesa to be built for Cygwin -with-driver=dri with indirect rendering only
>
>Various changes to enable mesa to be built for Cygwin -with-driver=dri with indirect
>rendering only rather than -with-driver=xlib
>
>Don't require all platforms to have LIBDRM, but introduce no_drm_is_fatal to make
>behaviour on platforms which expect to have DRM available the same as before, i.e.
>terminating configure with an error if DRM is not available
