I thought about this, but figured there weren't any 16-bit compilers
that would compile the rest of the code anyway. Are there any real
platforms where the compiler supports all that template machinery and
has 16-bit ints (maybe some configurations of gcc)? I suppose it
doesn't actually cost anything to go to unsigned long...
