Use GetLocaleInfo() on Windows to get the localized weekday and month

2005-11-28  Tor Lillqvist  <tml@novell.com>

	* gtk/gtkcalendar.c (gtk_calendar_init): Use GetLocaleInfo() on
	Windows to get the localized weekday and month names. strftime()
	in the Microsoft C library returns strings in the default codepage
	for the locale of the process, not the system codepage. Thus
	g_locale_to_utf8() isn't useable on the return value from
	strftime(). (#322603)
