Does this assert the equivalence of the types (just like a pointer 
assignment would do)?  Maybe at a comment to that effect?

I'm not sure if __WORDSIZE32_SIZE_ULONG is the right condition for that 
because it does not seem to govern the actual definition if 
size_t/ssize_t, but with the compile test to check for consistency, it's 
good enough, I think.

Thanks,
