Hmmm. That surprises me. From what I've learned here in this list, the low-
level-C grade should be faster. It's a mixture of C and assembler, whereas
the high-level-C is just C.

When installing the RODT verson of the compiler, it always says that you get
a faster compiler, when doing both compilation passes.
