Fixed bug #193 The attached patch is mostly cosmetic: Currently, we always add both -framework OpenGL and -framework AGL for Mac OS X command line builds. However, the former is only used for the Cocoa video driver, and the latter only for the Carbon video driver (as far as I can tell, at least). Hence the attached patch modifies configure.in so that each only gets added to the list of frameworks if the corresponding video driver is enabled.
