Woow, quite an achievement!

To be clear, this provides packages to perform DDC of GCC 4.7, right?

Did you choose 4.7 due to the fact that it’s the last C-only version?

Perhaps there are pieces that (reproducibility fixes, etc.) that are
generally useful and could be merged directly.

As for the DDC packages, I don’t know.  It would probably require some
cleanup and discussion, but I think it would make sense to add it in
Guix proper.  That would allow Guix users to test their compiler through
DDC, which is not negligible.

Thanks,
