I'd like to come up with something more portable. Unfortunately, if
configure needs to compile a program and run it, we end up limiting
ourselves to not cross compiling.

This is what happens when we check the size of various datatypes.

It turns out, we don't need that check, so I just removed it.

The only other check that I can think that is a problem is the check for
the endianness of the system.

I'll have to do some research to figure out if there is a way we can
determine that and allow cross compiles.
