[To Paul]
I downloaded a copy of your OpenGL wrapper today and tried to find
the problem. The crash seems to occur upon returning from the
Display() function which is used as a callback. I noticed from
Cube.c that Display(), Reshape(), and Keyboard() are all of the
type VOID meaning that Glut isn't expecting a return value.
The insistance by call_dll() that *function* must be called and
for it to return a value might be causing the stack to become
corrupted. That could cause the program to jump to a bad address
when a machine code RET pops one off the stack, causing the
"Invalid Instruction" error.

What do you think? Am I way off here? If not, any chance of a
fix?

Thanks,
