It would prbably be easier to change the TST_EXP_POSITIVE_ to return a
value instead of changing all the macros that expand to
TST_EXP_POSITIVE_.

Do we really need an return value from EXP_PASS and EXP_FAIL?

If TST_EXP_PASS_* does not break the test the return value was 0, if
TST_EXP_FAIL_* does not break the test, the return value was -1
