C ABI has been the same for ages, contrary to C++'s ABI which has
changed several times in the gcc 3 series, and changed again with
gcc4. There shouldn't be any problem using gcc4's compiled binaries
with older OSX, unless I'm missing smth.

I'll look into it when I have time. In the meantime, you'll have to
disable idct8.
