[Freeglut-developer] GLUT_XLIB_IMPLEMENTATION patch(ish)

[Jamie W. <ja...@sp...>]

So I'm also packaging a new version of PyOpenGL for Debian, and in the
build process it checks the value of GLUT_XLIB_IMPLEMENTATION to work
out what functions are available; the comments in the code suggest that
this #define had a finer granularity of API changes in the 3.x series.

Building against traditional GLUT results in a pyopengl module with a
complete set of functions, building against freeglut results in a module
that is missing useful functions such as glutFullScreen().

I made the following patch to include/GL/freeglut_std.h as I couldn't
find that macro anywhere in the source, and now the build of pyopengl
correctly detects the API.

This is against the 2.2.0 tarball from the sourceforget download page.
