/* Nov. 1, 2002
 *
 * Reworked setlocale() return values and locale arg processing to
 *   be more like glibc.  Applications expecting to be able to
 *   query locale settings should now work... at the cost of almost
 *   doubling the size of the setlocale object code.
 * Fixed a bug in the internal fixed-size-string locale specifier code.
 *
 * Dec 20, 2002
 *
 * Added in collation support and updated stub nl_langinfo.
