It would be interesting to have some speed results f2c/gcc vs. g77 for g94.

I compiled g94 with 0.5.21 and ist seems to work correctly.

BTW yesterday I compiled the new g77 0.5.22/gcc 2.7.2.3 and it doesn't have the
egcs array bug. On the egcs mailing list I read something about the unsolved
bounds problem. It might be that a recent snapshot fixes this bug. Does anybody 
know more about this topic?
