Don't crash if removing a nonexistent value.

1999-10-31  Tor Lillqvist  <tml@iki.fi>

* gcache.c (g_cache_remove): Don't crash if removing a nonexistent
value.

* gutils.c (gwin_getlocale): New Win32-specific function, returns
a Unixish current locale string (en, zh_TW etc).

* glib.h: Declare it.

* glib.def: Export it.

* testglib.c: Test it.

* gmessages.c (Win32: ensure_stdout_valid): Some improvements,
make sure we don't call AllocConsole several times, which I think
has happened.
