    What he's wanting is a standard C++ ABI. However, no operating system I'm
    aware of offers one. There are standard ABIs for other languages such as
    Objective-C (NeXT and Mac OS X) and C# (new windows) and Java (Sun), but I
    haven't seen a standard C++ ABI for Windows. Their ABIs are C-based. I
    think what you wanted is to link using -static and you forgot :)

    For an example of a great proprietary app that works great on many, many,
    many, many Linux distros, check out Mathematica. The key is the build
    process and installer - choice of compiler has little to do with it. The
    same Mathematica binaries run on pretty much every Linux out there.
