Thanks for all your testing work.  However, I think it is not ideal if
we add tests for regressions on branches other than where the
regressions occurred.  When we fix the regression, we want the test in
place right where the fix is needed, i.e., ideally on a new branch off
of the offending commit just like we'd do with a fix.

Am I gathering correctly that the
  src/foo.c: src/$(dirstamp)

rule lets GNU make build the thing in the wrong directory due to the
target lookup rules?

Have you analyzed this failure, and if yes, could you please explain it?

Thanks,
Ralf
