I'm not sure; most programs I've seen just use #include <gl.h> and seeing
this is what it was originally I've changed it back to that. I looked at
some SGI documentation on porting IRIS GL programs to Open GL and it
suggested you would have statements of the form #include <gl/gl.h>, which
needed to be changed to #include <GL/gl.h>. I would guess it was
originally just gl.h and the distinction came in when Open GL was introduced
(originally also just available on the SGI platform as far as I know).
