* gtk/gtkmain.c (do_pre_parse_initialization): On Win32, if
environment variable LC_ALL or LANG is set, set the Win32 thread
locale to the corresponding locale. Then call the C library
setlocale() to set the C library locale accordingly. The
inconsistency mentioned below is gone. (#339756) Do some special
casing for Serbia and Montenegro. Handle the Latin and Cyrillic
scripts for Azeri, Uzbek and Serbian.
(enum_locale_proc): Helper function for the above functionality.
* gtk/gtkcalendar.c (gtk_calendar_init): No longer need to check
if the environment variables are set here, as they have already
been taken into account and the Win32 thread locale has been
set.
