There's two approaches to this ugly problem.  One is as above, with the 
downside of increasing the number of global symbols.  The other is to 
link a Library's objects directly into a CppunitTest library via 
gb_CppunitTest_use_library_objects.  The downside there is that you need 
typically duplicate all the Library_*.mk's 
gb_Library_set/use/whatever... calls as gb_CppunitTest_... calls in the 
CppunitTest_*.mk.

Both approaches suck.  When possible, try to stick with the second one, 
though.
