    Fyi, another fact that was missing from the quoted thread: gcc 2.95
    catches bugs that 3.x compilers simply miss. Support for the old
    compiler is more work, no doubt, and at times requires to work around
    plain compiler bugs as well. But there is some return on investment.

    Is it worth the effort? Not sure. But the "it's old, drop support
    for it" argument just doesn't cut it and it doesn't get any better by
    repetition.
