Bonjour Eric,

Thanks for getting back to me so fast.

I don't think so. The Apple developer documentation states that gcc 4.0 
or later assume default visibility unless you explicity set the 
-fvisibility flag during compilation.

I tried this with the same result. Doing a make -n confirms that the 
visibility flag is set to default, e.g.:

 --green "Building CXX object libRTI/CMakeFiles/RTI.dir/RTItypesImp.o"
cd /Users/Mark/devel/Build_CERTI-3.4.0/libRTI && /usr/bin/c++

version 3.4.0. Sorry, I should have stated.
