how about the following patch. This is against the head, but I can
easily redo this on the 3.3 branch if that is desired and someone
can take care of the merging back to the head.

	* c-opts.c (COMMAND_LINE_OPTIONS): Add -Wunused-static-variable
	for finer grained warning control.
	* doc/invoke.texi: Document it.
	* flags.h: Declare warn_unused_static_variable.
	* toplev.c (W_options): Add it.
	(check_global_declarations): Use it.

IIRC -Wunused used to warn about this kind of thing. I've not been paying
attention. Has the -Wunused functionality been moved into -Wall, or is it
something else?

what is wrong with having this check in -Wunused?
