I'm open to suggestions on how to do this properly in Scheme; Wouldn’t SRFI-60 or Guile’s own operations (info "(guile) Bitwise Operations") do the job? I see you also have wrappers for C integer subtraction and addition, but the behavior of these upon overflow/underflow is undefined in the C standard (see ‘-fwrapv’ in GCC.) Thanks, Ludo’.
