More debugging information - in at least one of the failures, neither of

the "Wrote xxx" messages was printed, although the compiler appeared to
have been run on the .c file that was never claimed to have been
written, but got an error because it couldn't find the .h file (also
never claimed to have been written), and in one of the successes on the
same buildbot, they were both printed for the same file.
