OK, this has come up before: the standard *requires* that
std::messages<>::catalog is an int, and that on failure
std::messages<>::open returns a negative value.  However IBM in their wisdom
have made std::messages<>::catalog a pointer type, now I understand why
they're done this, but it makes it impossible to write portable code that
manipulates std::messages IMO.
