Subject: Math3D problems

After my previous batch of test failures I am now up to this point: tests
run but they fail. I had to fix a lot of problems with TestCase setup
methods being called set_up instead of setup, could that be an old naming?
My results now:

make test

---------------

159 tests, 1458 assertions, 2 failures, 2 errors

Those warnings won't be a problem. Errors 1 and 2 seems related to the
definition of the Errors, did anyone find out how the Math3D library is
initialized? This is where in the C code these errors are defined...
Failures 3 and 4 can be related, if no tests returns nil in 3 then 4 is a
possible result.

Any ideas? Unless the Error-problems are solved I can't use the library,
unfortunately. 

Thanks for your help,
Bart
