I just tried it again tonight; the current master branch has 3532
warnings when compiled with -Wextra, 1409 of which are -Wsign-compare
warnings. After applying the patch below, those numbers are reduced
by 344 to 3188/1065.

I'd love it if we were clean on -Wextra. My big question is many
contortions we'd have to go through in the code. I don't mind at all if
we're actually cleaning as we go (e.g., using types of the correct
signedness, or preventing possible funny interactions). I'm just worried
it will turn into a bunch of noisy casts.

Hmm, my memory is not what it was, ... ;-) However, I seem to recall
that most of the changes were "improvements", with only a (relatively)
few scattering of casts (behind existing macros - namely the OPTION
macros). (Oh, wait, I think 'unused' parameters etc., was another
problem area).

The patch you showed seems like an improvement to the code, but I don't
know if that would be the case for all of them. :)

Yes, I've had that patch (and others like it) hanging around for
years! (perhaps it's time to dig through all those old branches)

ATB,
