I have a couple of follow-up patches that I had developed while playing
with this.

There is a warning option for MSVC that appears to have a very similar
effect to the ones we added here, so I propose we add that one as well.

Additionally, there is an option for MSVC to disable warnings in system
headers, similar to the default behavior of GCC. This would be required
here because some system header files have non-strict prototypes.

Additionally, I propose to add -Wold-style-declaration, which is
completely unrelated to -Wold-style-definition, but it has popped up a
few times via the buildfarm (grep for it in git log), so I think we
might as well add it so that everyone sees it.

Finally, I think we can remove the option -Wendif-labels, which doesn't
do anything anymore that isn't the default. (It was only not the
default before gcc 4.0.)
