foo (a, b, dummy)
ARG_UNUSED (int, dummy);

So we won't be able to bootstrap from third-party C++ compilers?
The ATTRIBUTE_UNUSED macro cannot be made to work with MSVC, CW
or other popular compilers.
Not that I care that much: on any supported host you can always
install an older version of GCC or cross-compile from another host.
