Yes, exactly: “everything” depends on GCC, and GCC depends on GMP, MPFR,
and MPC.  Thus, upgrading one of these leads to a rebuild of everything.

The way to address it (as is done in Nixpkgs) is to have a staging
branch for such changes, and to merge it once in a while.  So now is the
time to inaugurate a new branch.  :-)

Would it be an option for you to send a ‘git format-patch’ kind of
patch?

Thanks!

Ludo’.
