config.h is generally generated from config.h.in by the configure script
(and the config.h.in is generated in some cases by autoheader), and the
values of those defines are generally based on autoconf test results, which
are often cached. By supplying different cached results to those tests, you
can change the emitted config.h without having to explicitly and manually
do so.
