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).
