Yes, unfortunately.  The right answer depends on what we want -std=c89
to do.  If we intend to use feature test macros to enable POSIX, the
test snippet should do so and then we'll use
PETSC_DESIRE_FEATURE_TEST_MACROS.  If we are trying to produce an
artificially-limited environment that can only be found on very obscure
and obsolete operating systems, then maybe we should have a
--with-feature-test-macros=0 option.

Indeed.

Is this a tagging experiment of yours?
