First of all, there are *two* copies of gl.c in the xforms distribution.
One is in the demos dir, it is a program, the other is in the FORMS dir,
it is the library extension code that you need. Take a look in the FORMS
dir, there are also two in there one for mesaGL and one for openGL,
although I tend to use the one for openGL even though I have mesa apps,
for general portability. just compile the code into a gl.o and link it in
to any program that uses the gl_canvas functions.
