Comment(by felix):
Well, I'm not sure what to do. Would it be acceptable to require 4.2 or
higher? As I understand, this option enables "normal" overflow of integer
arithmetic (2s complement), which I think (just think) is required for the
fixnum-overflow detection (Gambit uses this flag and I recall readinf
somewhere on its mailing list about the flag being "required for
correctness", whatever that means).
