i would be very interested in your preliminary results if you have any.

maybe your going to test 2.95.3 / 3.3.6 / 3.4.4 / 4.0.1  / 4.1.x with C based 
benchmarks, but i would be also very intrested in complex C++ (using stl 
features) for the same set of compilers, as my 'embedded' application is 
written in complex c++.
