Interesting: on my mac, GLhandleARB is defined as a void *.  Your patch
defines it as an unsigned long (which is equivalent to void * from an ABI
perspective).  GL defines it as an unsigned int, which is certainly *not*
equivalent on 64-bit systems.

This throws a bit of a monkey wrench into things, since it breaks some of
the aliases defined in the official gl.spec file.  for example
GetAttachedObjectsARB is marked as an alias for GetAttachedShaders, but
this can't possibly work on mac if one of them takes a GLhandleARB * as its
4th argument, and the other takes a GLuint * as its 4th argument (since the
two types have different sizes).

I'll do some investigation and see what's really going on.
