I'm having some trouble with the directions in README.txt in the OpenGL
docs. They indicate one should use "-lopengl32"; however, that's not working
for me. Here is the excerpt from my config.log:

---
configure:16198: gcc -o conftest.exe -g -O2 -I/usr/X11R6/include
conftest.c -lopengl32 -L/usr/X11R6/lib  -lm  >&5

# endif

# endif

#ifdef F77_DUMMY_MAIN
#  ifdef __cplusplus
     extern "C"
#  endif
   int F77_DUMMY_MAIN() { return 1; }
#endif
int
main ()
{
glBegin(0)
  ;
  return 0;
}

There's a similar problem with using -lglu32. However, -lGL works and -lGLU
works. So I wouldn't be complaining at all if I could figure out how to link
with glut. Neither "-lglut32 -lGLU -lGL" nor "-lglut -lGLU -lGL" works. Any
ideas?
