Please file individual bugs and have them block this one.
One common failure mode: "error: uint64_t does not name a type" (same with other int types)
Solution: add "#include <cstdint>" somewhere appropriate.
Should I block this bug from the bugs for GURU packages?

We tend not to do that for overlays.
