What is especially significant is that, while the average performance is 
almost identical, there's some very large (40% or more!) differences in 
several individual tests.  It would be interesting to know whether these 
tests have any practical implications (e.g., it might be that those tests 
use code which will rarely happen in real-world programs).

If the tests are of practical importance, I think it would be interesting
to know what are the cases where GCC-generated code is much slower than
Watcom's, and vice versa.  From time to time, people ask here questions 
about relative performance, and all we usually tell them is ``almost 
identical''.
