With options (b) or (c) you should get a warning when compiling for oglbase
since the prototype for glPointParametersfEXT would not be defined, assuming
we did what you proposed in gl.h

#if something
#include <GL/glext.h>
#else
#define GL_EXT_point_parameters 1
extern void glPointParameterfEXT(...);
#endif

This is one of the major advantages of (b) over (a).
