More or less like what GLEW does to encapsulate OpenGL (or was that another project, it's been a while I manhandled OpenGL...)? Such an approach shouldn't be (too) platform-dependent, and thus relatively straightforward to bring to other platforms, no?

I wasn't expecting anything else.

But:

FWIW, I think there might be interest in bringing X11/xcb support back to OS X, which could justify bringing those "similar features" on to OS X too. I'm not volunteering though (but wouldn't mind being paid for doing this either ;)).
