Are you sure about that? I mean if you are running the test suite,
then I think that you also are quite capable of recompiling Cairo with
the test API included.

Alright, there should now be a warning when typing make test, retest,
recheck, check, check-valgrind and perf. Note that you only get the
warning when you type the command in Cairo's root directory. That is,
if you enter the test directory and type make, you will still get a
compile error. Which is exactly what would have happened if Cairo was
configured without libpng.

I have fixed that I think.

Ok. I have merged the --enable-test-functions and
--enable-test-surfaces to --enable-test-build with the macro name
CAIRO_IS_TEST_BUILD and with your proposed name for the function.
Please review the attached patch.
