Well, the conversion is implementation-defined behavior, and GCC documents what
it does in that case (does it?) and thus you can rely on it, and given that
other compilers also have simimilar implementation-defined behavior choice for
that case, you can portably assume it unless you are targetting extinct
architectures.
