-/**
- * \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 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.
