I like 32 bits. Much larger than that, and hex just seems much more
natural.

As an alternative, I'd suggest 64-bits as the decimal limit. 64-bit types
are supported by most compilers (all modern ones I know of). Also we have
64-bit luns, so implementations will need some sort of 64-bit support as
it stands. Chances are that support will have addition and multiply, so
strtoull() wouldn't be too hard a thing to do.

Take care,
