Thank you for all of the feedback.
I agree that many of the failures are due to inadequate library
support, and we should eventually improve the tests to detect
the inferior interfaces and diagnose them as such. However,
that is not on my short list, for now.

I actually wrote a patch to fix the automake bug that led to this,
but did not find the time to write a stand-alone test case.
Today, I wrote the commit log entry and am attaching the
incomplete diff (no NEWS and no test) here, in case someone
wants to help move this along before I find time.
