It's been 0x000fffff on Mesa since the initial import in 1999. It's
the same value on my OS X 10.8 system, mingw's Windows-compatible
gl.h, and a copy of the windows SDK gl.h I found laying around on the
internet.
Fixes piglit ARB_multisample/pushpop.
On OS X, GLhandleARB is void *, which is of different size than GLuint
on 64-bit. Because of this, the implementation of
glGetAttachedObjectsARB must be different from glGetAttachedShaders,
since the pointers/ints are packed the output memory.
From Mesa:
/* The "Interactions with APPLE_vertex_array_object" section of the
* GL_ARB_vertex_array_object spec says:
*
* "The first bind call, either BindVertexArray or
* BindVertexArrayAPPLE, determines the semantic of the object."
