No extern "C" for XFree86 OpenGL headers

The XFree86 versions of the OpenGL headers files do not use extern "C"
when compiling C++ modules. This can result in linking errors as OpenGL
function receive decorated signatures that won't exist in the libraries.
A work around is for a developer to do something like the following in a
C++ code module:
#ifdef __cplusplus
extern "C" {
#include <GL/gl.h>
}
#endif
which shouldn't normally be necessary as other implementations of OpenGL
do not require this.
