2.0.3: * Fix segfault on emission of unconnected signal. * Test emission of unconnected signals in the test case. * Suppress compiler warning at dynamic_cast<>-test for good. (Help from Christof Petig and Timothy M. Shead.) 2.0.2: * Suppress compiler warning in compatibility module at dynamic_cast<>-test (fix suggested by Timothy M. Shead). * If a custom accumulator is specified invoke it on signal emission even if the signal's slot list is empty. (This used to be the case in libsigc++-1.2 as pointed out by Timothy.)
