I originally didn't have any fixes, I just ignored the warnings. I made
some fixes and, since I don't have a diff tool, am sending the altered files
as attachments. All I did was add forward declarations in
catch_exceptions.hpp and move the #includes in test_tools.hpp so the
declarations come before the definitions.
