refs #117 stub_impl_hack: defines a function otherwise provided by main.cpp remove old self_test.h contents (e.g. TEST); superceded by cxxtestgen TS_ASSERT etc. only include self_test from a test (otherwise, cxxtest include dir won't be set) cxxtest won't run tests named only "test"; add more descriptive name FIXES uncovered by self tests lib: infinite loop in log2 lockfree: incorrect params This was SVN commit r3979.
