You're comparing apples and oranges, since C (my code) and Java differ
in their definitions and implementations of floating-point.
I don't build gcj these days; however, when I have a moment later, I'll
build the latest GCC mainline from CVS -- with Java -- and see how it
reacts to my Java version of my benchmark. I also have a Fortran 95
version as well, so I guess I might as well try several languages, and
see what we get.
