In my opinion, if this is not a defect, then the only thing
that needs to be done is writing a few lines in some "Known Issues"
section of the documentation. This because, at least for me,
standard conformance is the first and foremost value.
By the way, I was not able to find the C Standard Defect Report
concerning this issue: do you have a pointer? It would be
interesting to have the advice of someone who is in the
standardization commitee.
So, a possible plan for dealing with this issue could be:
document it so that users can know about it;
when the standard has been clarified
if the standard implies INT_MIN % -1 should give 0
resume the discussion about how to implement that;
resume the discussion about the default behavior of GCC
else
do nothing
