Backward compatibility is exactly what you're seeing here.
g++ is warning you that your main function doesn't have one of the two
forms required by the C++ standard, but it's still compiling it.
You can even disable the warning with "-Wno-main".
BTW, the warning is slightly misleading. It's not emitted if main is
defined with 3 parameters (argc, argv, envp).
