It works fine with #defines instead of enums, but the other problem
is that by defining GLenum as a real enum, you also get the problem
that the following oft-used idiom:
GLint mmode;
glGetIntegerv(GL_MATRIX_MODE,&mmode);
...
glMatrixMode(mmode);
no longer works in g++ 2.95.2 without a cast:
glMatrixMode((GLenum)mmode);
The solution would be to redefine all of the GLenums as #defines, and
change GLenum to be:
typedef unsigned int GLenum;
as in the IRIX gl.h. Does this make sense?
