Well, actually it'll depend on a number of factors. I suspect the
result is literally "undefined" from the standards point of view. In
many systems I suspect it will be confused with a signal having been
delivered. In all cases I suspect there's only one chance in 127 of the
overflow resulting in an apparent success. I'm too lazy to write the
trivial test case though.... :-)

What a bogus worry! Do you have an example of an actual code path in
CVS which can easily cause such an overflow?
