No such automation exists.  I expect that it would be dwarfed by the
work needed to adjust the actual sources for all the new tests, too
(i.e., adding '#ifdef HAVE_SOME_HEADER_H' where needed, and such).

BTW, I'd introduce new configure tests only when I know or strongly
suspect them to actually fix a portability issue; and I'd still try
hard to find a platform that exposes the non-default test result, to
make sure not to rely on other unnoticed assumptions.

Hope that helps.

Cheers,
Ralf
