This really looks like a problem of the Standard Library specification
to me and
a corresponding issue should be submitted. In fact the wording can be
interpreted
that mixing <cstdlib> with <cmath> would imply two different versions of
std::abs(int) because of different required return types. I will
prepare a corresponding
submission to the LWG.
