Odd.  Wonder what makes gcc output that, and if there is a way to work
around it besides explicitly excluding -Wstack-protector in configure.ac?

Oh, I think I see a way.  In branch-1.6, I used re_compile_fastmap instead
of manually probing all 256 bytes to see if they would match the regex.
I'll see about back-porting that to branch-1.4.
