This is also what is on the Solaris system I was using. gcc -E showed
that the #else branch was being taken. The #if branch is taken when
compiling in 64-bit mode (gcc -m64).

We're fine so long as everything casts to either int or long. I only saw
warnings from a couple of places that did not do a cast at all.
