- I've heard stories from f2c producing 30% faster code then a
- vendor's compiler to 30% slower code than the vendor's compiler. I've
- not heard stories of f2c being _much_ less efficient, where for me
- much less efficient means a factor of 2 (100%) more or less efficient.
- IMHO, f2c is a darn good compiler, on any platform.
