The procedure is not secret. I just do a complete, clean rebuild of ~200
MinGW packages with the new headers. Some of these packages (SDL,
GStreamer, GTK+) make use of OpenGL. If all packages compile without
problems, i judge the headers fit for pushing into master.
I haven't updated my packages for almost 2 years now, so no rebuilds ->
no OpenGL header updates.
You can probably do something similar with MSYS2 or any other package
system. Just update the headers and rebuild everything.
Packages that use GL:
glew
freeglut
gst-plugins-bad (the gl plugin)
opencv
tiff (the tiffgt program)
webp (vwebp program)
gtk+ (gtk3-demo program, OpenGL demo)
SDL (though it's possible for GL parts to not to be built, i guess)
