Yes, 4.0 and 4.2 should work out of the box.

Where this g++ 4.4.comes from? I've had more luck on OS X 10.5 with gcc 4.5 from 
MacPorts, and configured it this way:

using darwin : 4.5 : /opt/local/bin/gcc-mp-4.5 : <cxxflags>\"-Wno-long-long\" 
<linkflags>\"-L/opt/local/lib\" ;

You could have g++ instead of gcc I have above; I had to write gcc due to other 
reasons caused by some complicated project requirements/setup.

Even though that isn't an Apple gcc, 'using darwin' works better than 'using 
gcc', the only issue I had with 'using darwin' was just "unrecognized option 
'-no-cpp-precomp'" warnings, but otherwise it was fine.

HTH,
