Nice to see that you've added something to the test suite to prevent 
this same problem from being re-introduced during future development. 
:-)

One question about the test, though: are those linker flags simply 
ignored by non-gcc compilers? I don't see anything in the CMakeLists 
file for the test that determines whether the linker interprets 
-Wl,--start-group etc. properly...?


Thx,
