Another possibility might be to pop up a dialog box for those errors; I
have a patch to do that, although:

	on UNIX/X, one might want to do that only if the standard output
	isn't a terminal, or if you're not running from a
	terminal/terminal emulator, or something such as that;

	on Win32, one might want to do that only if the program is built
	with "/subsystem:windows" rather than "/subsystem:console" (i.e,
	if "WinMain()" was called).
