From 5dcc4c2e25452b932e3c45bf25cfb89db461bba7 Mon Sep 17 00:00:00 2001

Subject: Added some temporary "stubs" for collation.   strcoll is an alias for
 strcmp.   strxfrm is an alias for strlcpy.   wcscoll is an alias for wcscmp. 
  wcsxfrm is implemented as a wchar version of strlcpy. Real locale-dependent
 implementations are coming soon.
