- * Revision 1.17 2004/08/24 13:32:14 bernie
- * PP_CAT(), PP_STRINGIZE(): Move back to compiler.h to break circular dependency between cpu.h/compiler.h/macros.h;
- * offsetof(), countof(): Move back to compiler.h to avoid including macros.h almost everywhere;
- * Trim CVS log;
- * Rename header guards;
- * Don't include arch_config.h in compiler.h as it's not needed there.

- * Revision 1.16 2004/08/14 19:37:57 rasky
- * Merge da SC: macros.h, pool.h, BIT_CHANGE, nome dei processi, etc.

- * Revision 1.15 2004/08/13 03:23:26 bernie
- * Adjust a few MSVC tweaks from older projects.
- *
- * Revision 1.14 2004/08/10 06:56:29 bernie
- * RESTRICT: New C99-like macro; STATIC_ASSERT: Fix warning for multiple invocation in one file.
