If I got Markus right, his problem was not that he had to export a method, but
that somebody changed unittests from static linking the library it tests to
dynamic linking. I wholeheartly agree: A unittest should be allowed to see the
internals of what it tests -- esp. as the "unit" is something way smaller that
one of our (huge) libraries.

If you care about the size of the build output(*), make the "unit" that the test
tests able to be standalone, so that only that subset needs to be statically
linked into the unittest. Thats a big harder, but something that would benefit
the codebase as a whole (decoupling FTW etc.).

Best,
