Hmm, a factor of 3 speedup, but your numbers with -fno-gcse are in line with mine by a ratio of clock speed and close to what I remember seeing on a G3 at a similar clock speed. Unfortunately, I left that piece of paper at work, but what's way out of line is your measurements without the -fno-gcse flag. I can't recreate them, so I wonder if there's something on your system that's slowing it down. I almost always do clean installs, especially if I had done some extra stuff, like installing fink stuff.
Do you have some way to do a clean install? Even if it's on an external drive, the goal is to build GForth on a clean OSX 10.2. If you still see a difference there, then we have something to investigate. Otherwise, it's going to be hard to track this down. If you have fink installed, you might try renaming the /sw directory, but other stuff might be harder to isolate. What does the -fno-gcse flag turn off anyway?
