In reference to the message thread starting at http://gcc.gnu.org/ml/gcc/2003-04/msg01494.html
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?
