fixes #564. Testing if boost is using long long. Testing to compile some code similar to the problematic one in and particuarly we include . The test is specific to GCC in the sense that -pedantic and -Werror are specific to GCC. In the case of using any other compiler the compilation test will still run and will likely run successfully. In any case the flags -pedantic -Werror and -Wno-long-long are added through YAT_CXX_ADD_FLAG, which implies the flags will only be added when the compiler supports it. I'm afraid the variable names (AM_CXXFLAGS) has changed in trunk, so the merge will need some massage.
