/**
 * \file glheader.h
 * Top-most include file.
 *
 * This is the top-most include file of the Mesa sources.
 * It includes gl.h and all system headers which are needed.
 * Other Mesa source files should \e not directly include any system
 * headers.  This allows Mesa to be integrated into XFree86 and
 * allows system-dependent hacks/workarounds to be collected in one place.
 *
 * \note Actually, a lot of system-dependent stuff is now in imports.[ch].
 *
 * If you touch this file, everything gets recompiled!
 *
 * This file should be included before any other header in the .c files.
 *
 * Put compiler/OS/assembly pragmas and macros here to avoid
 * cluttering other source files.
