New Win32-only function. Use the wide character Win32 API to do the work

2007-02-17  Tor Lillqvist  <tml@novell.com>

	* glib/gdate.c (win32_strftime_helper): New Win32-only
	function. Use the wide character Win32 API to do the work of
	strftime(): GetThreadLocale(), GetLocaleInfoW(), GetDateFormatW()
	and GetTimeFormatW().
	(g_date_strftime): On Windows use win32_strftime_helper()
	instead of strftime() to avoid codepage issues with strftime().
	Unfortunately using wcsftime() would not help either. (#404832)
