Comment 10 for bug 992217

Micah, that's more or less what I'm thinking, not a separate transitional binary package since gcc-mingw-w64 still exists, but making gcc-mingw-w64 recommend the various other compiler packages which used to be part of it (so g++-mingw-w64, gfortran-mingw-w64 and gnat-mingw-w64). Would that be sufficient? I'd rather avoid having a strong dependency since the whole point of the split was to allow users to only install the compilers they actually want...
