Now everything works fine, except this brings up another issue with wglGetProcAddress. The problem is that all gl extensions function pointers are declared WINAPI, and indeed this is what type of functoin wglGetProcAddress is expected to return. However for extensions that are not registered in opengl_ext.c wglGetProcAddress falls back to glXGetProcAddressARB which would return a non-WINAPI function pointer. After the first call to such a function we would have corrupted the stack. There doesn't seem to be a nice way to fix this that I can think of. wglGetProcAddress should never return a non-WINAPI function though, as that is just asking for trouble. Better to return NULL instead of falling back to glXGetProcAddressARB.
Maybe it'd be possible to make a wrapper function -- a WINAPI function pointer that just does a call to this glXGetProcAddressARB ?
(Just me thinking aloud ;-) )
