Looks like it's coming from src/template/osf. If Douglas can confirm
that a lower -O level makes the compiler complaint go away, then we need
to change that template.
BTW, the other arm of the osf template looks pretty bogus too: isn't it
forcing no optimizations for gcc? I'd have expected CFLAGS=-O2 for gcc.
