[Win32] Don't open a console window if standard output or standard error

Browse Source 
2004-09-22  Tor Lillqvist  <tml@iki.fi>

	* glib/gmessages.c: [Win32] Don't open a console window if
	standard output or standard error are invalid (as they are for GUI
	applications). These console windows that open up unexpectedly
	have caused endless amounts of confusion among end-users.

	Don't output the process id on Windows. Only output the program
	name. If not set with g_set_prgname(), fetch the application
	executable's name and use that.
