I believe we depend on the reasonable/GCC modulo behaviour in many paths.
Sometimes it is even more or less enforced by the underlying libraries. For
instance, iconv() returns (size_t)-1 on error.
So even though I cannot find any such warranty in POSIX, I think we should
continue to rely on the GCC behaviour for lack of any reasonable alternative.
