Eliminate remaining gcc warnings Various one-liners (mostly removing unused variables) to make the code safe for the full set of warnings used by the xorg macros. On Debian-based systems, flex generates incorrect code resulting in two warnings about yy_getcolumn and yy_setcolumn having no previous declaration despite being non-static. Fedora carries a patch to fix this, and a bug has been filed on Debian's flex to add the patch: http://bugs.debian.org/667027 Aside from this, it's now safe for --enable-strict-compilation.
