  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.
  38  *
  39  * If you touch this file, everything gets recompiled!
  40  *
  41  * This file should be included before any other header in the .c files.
  42  *
  43  * Put compiler/OS/assembly pragmas and macros here to avoid
  44  * cluttering other source files.
