I removed the check for the function and now the Makefile is perfectly
generated and make works flawlessly. Make test fails however:

make test
ruby test.rb
/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in
`require__': ./tests/Vector.tests.rb:556: no .<digit> floating literal

                                                                          ^

                        expected = vec.to_a.inject(0) {|x,y| x+(y*y)}.**(.5)
                                                                          ^

        from /usr/lib/ruby/1.8/find.rb:38:in `find'
        from test.rb:20
make: *** [test] Error 1

Turning .5 into 0.5 fixed that. Afterwards I got this error:

make test
ruby test.rb
./tests/Matrix4.tests.rb:32: warning: default `to_a' will be obsolete
./tests/Bound.tests.rb:30: warning: default `to_a' will be obsolete

        from test.rb:53:in `new'
        from test.rb:53
make: *** [test] Error 1

(I'll ignore the to_a warnings, those tests work)
But the suite method add is missing, I replaced it with the << method in
test.rb:
ObjectSpace.each_object( Class ) {|klass|
                                suite << klass.suite if klass < Test::Unit::TestCase
                        }

Next my tests ran, without good results:

make test
ruby test.rb
./tests/Matrix4.tests.rb:32: warning: default `to_a' will be obsolete
./tests/Bound.tests.rb:30: warning: default `to_a' will be obsolete
./tests/Require.tests.rb:27: warning: parenthesize argument(s) for future

  1) Error:

NoMethodError: undefined method `each' for nil:NilClass
    ./tests/Ortho.tests.rb:65:in `test_00_7_contains?'
    ./tests/m3dUnitTest.rb:63:in `run'

Somehow the setup methods don't work? It seems there is something wrong with
the testsuite, but I don't see what...
