Yes, reducing #ifdefs is my concern.
If I understand right, if you have a piece of code that could be running
under both desktop GL and ES, you'll want to know what kind of version
number al_get_opengl_version() is giving you. Otherwise you don't know
what you are comparing (without resorting to #ifdefs).
