33 * This is the top-most include file of the Mesa sources.
34 * It includes gl.h and all system headers which are needed.
35 * Other Mesa source files should _not_ directly include any system
36 * headers. This allows Mesa to be integrated into XFree86 and
37 * allows system-dependent hacks/work-arounds to be collected in one place.
39 * If you touch this file, everything gets recompiled!
41 * This file should be included before any other header in the .c files.
43 * Put compiler/OS/assembly pragmas and macros here to avoid
44 * cluttering other source files.
