+/* May 23, 2002     Initial Notes:
+ *
+ * I'm still tweaking this stuff, but it passes the tests I've thrown
+ * at it, and Erik needs it for the gcc port.  The glibc extension
+ * __wcsnrtombs() hasn't been tested, as I didn't find a test for it
+ * in the glibc source.  I also need to fix the behavior of
+ * _wchar_utf8sntowcs() if the max number of wchars to convert is 0.
+ *
+ * UTF-8 -> wchar -> UTF-8 conversion tests on Markus Kuhn's UTF-8-demo.txt
+ * file on my platform (x86) show about 5-10% faster conversion speed than
+ * glibc with mbsrtowcs()/wcsrtombs() and almost twice as fast as glibc with
+ * individual mbrtowc()/wcrtomb() calls.
+ *
+ * If 'DECODER' is defined, then _wchar_utf8sntowcs() will be compiled
+ * as a fail-safe UTF-8 decoder appropriate for a terminal, etc.  which
+ * needs to deal gracefully with whatever is sent to it.  In that mode,
+ * it passes Markus Kuhn's UTF-8-test.txt stress test.  I plan to add
+ * an arg to force that behavior, so the interface will be changing.
+ *
+ * I need to fix the error checking for 16-bit wide chars.  This isn't
+ * an issue for uClibc, but may be for ELKS.  I'm currently not sure
+ * if I'll use 16-bit, 32-bit, or configureable wchars in ELKS.
+ *
+ * July 1, 2002
+ *
+ * Fixed _wchar_utf8sntowcs() for the max number of wchars == 0 case.
+ * Fixed nul-char bug in btowc(), and another in __mbsnrtowcs() for 8-bit
+ *    locales.
+ * Enabled building of a C/POSIX-locale-only version, so full locale support
+ *    no longer needs to be enabled.
+ *
+ * Nov 4, 2002
+ *
+ * Fixed a bug in _wchar_wcsntoutf8s().  Don't store wcs position if dst is NULL.
+ * Also, introduce an awful hack into _wchar_wcsntoutf8s() and wcsrtombs() in
+ *   order to support %ls in printf.  See comments below for details.
+ * Change behaviour of wc<->mb functions when in the C locale.  Now they do
+ *   a 1-1 map for the range 0x80-UCHAR_MAX.  This is for backwards compatibility
+ *   and consistency with the stds requirements that a printf format string by
+ *   a valid multibyte string beginning and ending in it's initial shift state.
+ *
+ * Nov 5, 2002
+ *
+ * Forgot to change btowc and wctob when I changed the wc<->mb functions yesterday.
+ *
+ * Nov 7, 2002
+ *
+ * Add wcwidth and wcswidth, based on Markus Kuhn's wcwidth of 2002-05-08.
+ *   Added some size/speed optimizations and integrated it into my locale
+ *   framework.  Minimally tested at the moment, but the stub C-locale
+ *   version (which most people would probably be using) should be fine.
+ *
+ * Nov 21, 2002
+ *
+ * Revert the wc<->mb changes from earlier this month involving the C-locale.
+ * Add a couple of ugly hacks to support *wprintf.
+ * Add a mini iconv() and iconv implementation (requires locale support).
+ *
+ * Aug 1, 2003
+ * Bug fix for mbrtowc.
+ *
+ * Aug 18, 2003
+ * Bug fix: _wchar_utf8sntowcs and _wchar_wcsntoutf8s now set errno if EILSEQ.
+ *
+ * Feb 11, 2004
+ * Bug fix: Fix size check for remaining output space in iconv().
+ *
+ * Manuel
