But let me double-check that -Wextra is different than -W -- the
manual says they are the same but I could have sworn I've seen
it emit warnings not seen without it:
http://gcc.gnu.org/onlinedocs/gcc-4.0.2/gcc/Warning-Options.html#index-W-240
They really are the same -- below is the code from gcc 4.0.2 opts.c.
I removed the option from gcc.config with r367459.
708 case OPT_W:
709 /* For backward compatibility, -W is the same as -Wextra. */
710 set_Wextra (value);
711 break;
712
713 case OPT_Wextra:
714 set_Wextra (value);
715 break;
