Yes, that of course works as well.  With the basic C TAP library, you can
use plan_lazy() instead of plan() and the library will then figure out the
number of tests for you.

SOURCE and BUILD are only not set when you're building the C TAP Harness
source out of its distribution tarball, since that creates a generic
runtests binary.  When incorporating the test framework into another
package, you would do (from README):

        check_PROGRAMS = tests/runtests
        tests_runtests_CPPFLAGS = -DSOURCE='"$(abs_top_srcdir)/tests"' \
                -DBUILD='"$(abs_top_builddir)/tests"'

which will take care of defining SOURCE and BUILD, and then tests/runtests
-o <test> will work as expected.
