/* 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.
 *
 * Aug 1, 2003
 * Added glibc-like extended locale stuff (newlocale, duplocale, etc).
 *
 * Aug 18, 2003
 * Bug in duplocale... collation data wasn't copied.
 * Bug in newlocale... translate 1<<LC_ALL to LC_ALL_MASK.
 * Bug in _wchar_utf8sntowcs... fix cut-n-paste error.
 *
 * Aug 31, 2003
 * Hack around bg_BG bug; grouping specified but no thousands separator.
 * Also, disable the locale link_warnings for now, as they generate a
 * lot of noise when using libstd++.
 */
