Also note the tests were performed running in Thumb (not ARM)
mode.  Also there is not comment about thumb-interworking.
gcc does not mix ARM and Thumb modes for a single C source file,
so there maybe some extra overhead with the thumb-interworking
code for gcc that is not needed by the other compilers.

It would have been nice if the code was just straight ARM mode
(but the results may not have been nearly so dramatic).

Our testing reveals that GCC for ARM isn't that slow and is being
portrayed in a less-than-flattering light.  Michael has data on the
various ARM cores and their Dhrystone ratings.
