The most complex problems were from dealing with switches reverted in
the meantime (gcc5, gmp6, ncurses6).
It's likely that darwin is (still) broken nontrivially.

+      when you commit them, and automatically decrypted when you check them
+      out. The process will degrade gracefully, so even people without your
