Build some files with -Wno-tautological-compare?

The problem with the solutions I've seen proposed is that they just
wait for the compiler to get smarter, or the -O level to be raised, and
then we are back where we started.  It also makes elegant code less
-elegant.

I know there are advantages to finding these things elsewhere, but it
frustrates me when changes like this are need (mostly the follow-up
patches, if we just had to change the inside of the macros I wouldn't
mind so much).
