* $Log$
+ * 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.
+ *
+ * Revision 1.13 2004/08/02 20:20:29 aleph
+ * Merge from project_ks
+ *
+ * Revision 1.12 2004/08/01 01:21:17 bernie
+ * LIKELY(), UNLIKELY(): New compiler-specific macros.
+ *
+ * Revision 1.11 2004/07/30 14:34:10 rasky
+ * Vari fix per documentazione e commenti
+ * Aggiunte PP_CATn e STATIC_ASSERT
+ *
+ * Revision 1.10 2004/07/30 14:15:53 rasky
+ * Nuovo supporto unificato per detect della CPU
+ *
+ * Revision 1.9 2004/07/29 22:57:09 bernie
+ * vsprintf(): Remove prototype for backwards compatibility with GCC 3.4; ssize_t: Add definition for inferior compilers.
+ *
* Revision 1.8 2004/07/20 23:43:39 bernie
* Use attribute((always_inline)) to force inlining. This fixes the much
* hated need of redundant prototypes for inline functions.
