Hi all,
        One thing I've found works is to compile a 64-bit dummy binary at
patch-time or configure-time.

% echo "int main(int, char*[]) { return 0; }" > test64.cc
% g++ -m64 test64.cc -o test64
% ./test64 > /dev/null 2>&1

the execution will fail if 64-bit is unsupported.  Does this suffice?

I was able to test an early draft of your gcc4 packaging that way (back
when we wanted to conditionally --disable-multilib).

Maybe even useful as a pseudo-package for 64b dependency tracking?
