IIRC, in gcc-land you have to give both noreturn and nothrow

Are you sure? I was under the impression that GCC did not do this
because it interferes too much with debugging.
I'm not sure at all. I remember needing to use nothrow somewhere that
throw() didn't cut it, and could well have got the details wrong, and
the compiler has moved on anyway.
Furthermore, glibc marks abort as nothrow and noreturn, which is a bit
dubious, considering that it is perfectly fine to throw exception from
synchronously delivered signals.
Hm, that seems contradictory ...
