Were you able to figure out the discrepancies posted here?
http://gcc.gnu.org/ml/gcc/2004-08/msg00901.html

Also:
"Performance on alma was dramatically improved by disabling the inline
 mathematical functions (sin, cos) in glibc, and replacing them with
 inline code generated directly by GCC. This is how the Intel compiler
 operates at higher optimization levels; while GCC has not quite
 reached the performance of its commercial competitor, results on
 these benchmarks suggest that the new "tree-ssa" architecture holds
 great promise for improved code generation."

It's not clear from this whether the numbers you posted include
disabling the math functions or not.

(I really need to get access to an x86-linux box again.)
