I've run dhrystone using both the Aztec and Microsoft C compilers under 
"good ole" (:-) MS-Dos.  You can compile it with flags for either register or
no register execution (also with direct structure assignments as well as
memcpy's).  Aztec C was about twice as fast as Microsoft during execution
of the .EXE's generated (in fact, the Aztec C LARGE memory model was about
1 1/2 times as fast as the Microsoft SMALL model!).  Either Aztec has done
something incredibly right with their compiler or the dhrystone benchmark
is written in such a way as to "favor" Aztec's compiler (a longshot
considering how the benchmark evolved).
