c++/2183: gcc-3_0-branch compiles 2x slower than 2.95

Synopsis: gcc-3_0-branch compiles 2x slower than 2.95

State-Changed-From-To: open->closed
State-Changed-By: bangerth
State-Changed-When: Fri Nov  1 17:40:57 2002
State-Changed-Why:
    I think a compile-time regression in this range must be
    expected due to the switch to libstdc++ v3 alone. Add some
    new optimizations, and you're there, so I think one should
    classify this as "more features make things slower".
    
    Needless to say that I do not find the general trend too
    good either...
