Amar Takhar 61656d633b * Make GL_EXT() a noop on OS X, it's not required.
* Conditionalise glMultiDrawArraysFallback since it's not used on OS X.
 * Stub APIENTRY at the top of visual_tool_vector_clip.cpp, this should never be added to a header but at the top of source files.

Originally committed to SVN as r4737.
