Andrew,

Thanks for the reply.  For the small case demonstrating the problem, I
included it in the original message:
   http://www.cs.utsa.edu/~whaley/mmbench4.tar.gz

and have uploaded it as an attachment.  I am not sure what you mean by
"fully a target issue".  Perhaps I have submitted to the wrong area of
gcc performance bug?  Note that it is not limited to one machine: the
gcc 4 code is inferior to gcc 3 on both AMD and Intel.  I chose the
two newest machines I have access to, but I believe it is true for
older machines as well . . .

Any clarification appreciated,
Clint
