That would be very useful.

1) Easy: run a script to find affected packages and auto-file bugs.
2) Fairly possible: get at least the important packages fixed in F19
(or, 1+2: change default build configuration to cover most packages,
and rebuild.)

3) Difficult to do right now? set up an automated test to ensure new
packages are also covered and there are no regressions.
