Good point.  That means we want to run many of the tests once with -DNDEBUG
and once with -UNDEBUG.  In both cases we want to always enable those misused
asserts in the testing code.  We could do that in the following way:

 - introduce a macro unittest_assert() which is always enabled and use that in
   the relevant testing code.  Or use "if(!...) abort();" or similar.

 - when compiling with -DENABLE_DEBUG forcibly undefine NDEBUG in the test

 - when compiling with -DDISABLE_DEBUG forcibly define NDEBUG in the test

 - otherwise, leave NDEBUG untouched.

We can put that stuff in a header.  But we should use seperate headers for
unittest_assert() and the NDEBUG-fiddling, since the latter needs a very
specific position in the list of includes.

Are all corner-cases covered by this scheme?
