2000-08-27  Tor Lillqvist  <tml@iki.fi>

	* giowin32.c (g_io_channel_win32_poll): New function, otherwise
	like g_io_channel_win32_wait_for_condition(), but accept several
	GIOChannels.
	(g_io_channel_win32_wait_for_condition): Call
	g_io_channel_win32_poll().

	* glib.h: Declare g_io_channel_win32_poll().

	* gwin32.c (g_win32_error_message): Don't believe return value
	from FormatMessage.
