--- Comment #8 from Stefan Dösinger stefan@codeweavers.com --- These lines exist at least since 2012 according to git blame (where e834c920e moved them around), and if my memory serves me right I added them even earlier when I added GL_ARB_map_buffer_range support. It's just a precaution that we don't have both extensions enabled at the same time.
OSX only supports GL_ARB_map_buffer_range in core contexts, in legacy contexts we use GL_APPLE_flush_buffer_range. Wine uses legacy contexts unless you explicitly enabled core contexts (e.g. for d3d10/11) in the registry because some rarely used blit operations still rely on immediate mode draws.
