/* Dec 20, 2002
- *
* Initial test implementation of strcoll, strxfrm, wcscoll, and wcsxfrm.
* The code needs to be cleaned up a good bit, but I'd like to see people
* test it out.
+ *
+ * Sep 11, 2003
+ * Patch by Atsushi Nemoto <anemo@mba.ocn.ne.jp> to do arch-required
+ * mapping of signal strings (alpha, mips, hppa, sparc).
