The C++ "make check" tests now launch the test broker on a dynamic port (with --port 0), so multiple build on a single host won't be fighting over the standard AMQP port.
To enable that, all the test clients now take a standard set of options from the command line or from env. variables, the --help option will show you the options. The option parser is cleaned up a bit to be simpler to reuse. Cheers, Alan.
