-/* April 1, 2002
- * Initialize thread locks for fake files in vsnprintf and vdprintf.
- * reported by Erik Andersen (andersen@codepoet.com)
- * Fix an arg promotion handling bug in _do_one_spec for %c.
- * reported by Ilguiz Latypov <ilatypov@superbt.com>
- *
- * May 10, 2002
- * Remove __isdigit and use new ctype.h version.
- * Add conditional setting of QUAL_CHARS for size_t and ptrdiff_t.
- *
- * Aug 16, 2002
- * Fix two problems that showed up with the python 2.2.1 tests; one
- * involving %o and one involving %f.
- *
- * Oct 28, 2002
- * Fix a problem in vasprintf (reported by vodz a while back) when built
- * without custom stream support. In that case, it is necessary to do
- * a va_copy.
- * Make sure each va_copy has a matching va_end, as required by C99.
- *
- * Nov 4, 2002
- * Add locale-specific grouping support for integer decimal conversion.
- * Add locale-specific decimal point support for floating point conversion.
- * Note: grouping will have to wait for _dtostr() rewrite.
- * Add printf wchar support for %lc (%C) and %ls (%S).
- * Require printf format strings to be valid multibyte strings beginning and
- * ending in their initial shift state, as per the stds.
- *
- * Nov 21, 2002
- * Add *wprintf functions. Currently they don't support floating point
- * conversions. That will wait until the rewrite of _dtostr.
- *
- * Aug 1, 2003
- * Optional hexadecimal float notation support for %a/%A.
- * Floating point output now works for *wprintf.
- * Support for glibc locale-specific digit grouping for floats.
- * Misc bug fixes.
- *
- * Aug 31, 2003
- * Fix precision bug for %g conversion specifier when using %f style.
- *
- * Sep 5, 2003
- * Implement *s*scanf for the non-buffered stdio case with old_vfprintf.
- *
- * Sep 23, 2003
- * vfprintf was not always checking for narrow stream orientation.
- */

-/* TODO:
- *
- * Should we validate that *printf format strings are valid multibyte
- * strings in the current locale? ANSI/ISO C99 seems to imply this
