Thinking about it I can agree that string compare is good
enough. The only problem a strcmp would have are leading
zeros, and those are disallowed in version numbers and
checked for early.

Yes.  As Lars pointed out,
simply doing the comparison
on strings scales fine.

Do we really wish to extend version numbers beyond 32 bit ?
I.e. allow bignums ?
Did we discuss this ?
