However, the MacOSX Cocoa header `gltypes.h` defines it as `void*`. This causes a conflict. Both GLEW (https://sourceforge.net/p/glew/bugs/206/) and glLoadGen (https://bitbucket.org/alfonse/glloadgen/issue/33/mac-compilation-error) have encountered this issue, and simply ifdef-ing around `gltypes.h` is probably not a reliable solution. You should get with Apple and figure out what they want their GLhandleARB to be defined as, and provide an appropriate #ifdef around it for other platforms.
