Tor Lillqvist e4581869b4 Use the Win32 thread locale's first day of week setting on Win32.
2006-10-07  Tor Lillqvist  <tml@novell.com>

	* gtk/gtkcalendar.c (gtk_calendar_init): Use the Win32 thread
	locale's first day of week setting on Win32. (#339752, Bogdan
	Nicula) Don't do this if one of the environment variables that
	affect gettext is set, though. In that case use the week start day
	from the corresponding message catalog.

	Unfortunately the same logic isn't possible in the weekday and
	month name lookup; there even if you have set one of the
	aforementioned environment variables, you still get the weekday
	and month names from the Win32 thread locale. Yes, this is
	inconsistent.

	Use only wide-character API in the Win32 code in this file, too.
