After digging in the archives I see that most of those failures can
be blamed on using Apple's ancient m4, and the tests on my other
machine confirm that using MacPorts' m4 instead fixes them.
But there's still these two failures:

509: AC_CHECK_HEADER_STDBOOL                         FAILED (acheaders.at:9)
514: AC_HEADER_STDBOOL                               FAILED (acheaders.at:14)

AFAICT, the AC_HEADER_STDBOOL macro does actually work and give
the right answer (ie, that stdbool is pretty std), so I don't
understand why the test cases are failing.
