Yes. I use the MacPorts setup which sets

    --enable-languages=c,c++,objc,obj-c++,lto,fortran

Well, my testsuite runs are based on the GCC-7.2.0 release, plus some or all of
the patches in attachment 42124.

That's fine; just keep in mind that the patch has not been covered in my tests
because Ada has not been enabled there. To me, it looks like patch 4 should be
necessary for Darwin 8 (Tiger) and Darwin 9 (Leopard) if Ada is built, but that
is just a guess.
