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