That's why I continue to use 2.95.3, and probably will continue to use 
it for the remainder of my career, whenever I am free to make that choice.

That kind of slowdown is HUGE.

I wonder if I can ask, without offending any of the hard-working 
developers of gcc: Has anyone made a study of just why gcc got so slow 
after 2.95.3, and whether any profiling has been done to improve this?
