No, this is relevant for all GNU C compilers! Without this step, which replaces the switch statement of the interpreter with a jump table, you get a *much* slower VM. I suggest to use the latest SVN source.

Does it mean latest SVN source is already "Gnuified" ? ��With latest rev. I have a little drop in benchmarks. However I'd rather put a stable release for Pharo 1.0 than latest trunk. What do you think ?
