Here are the cstream results for some Mac systems that I have at home.
The oldest machine is a 1989 vintage Mac.
The compilers used were from Metrowerks Codewarrior DR6, all optimisations on.
I wanted to try cstream on my 1984 vintage Mac 512KE, but I have to dig out
an older compiler and libraries that will run under System 6.0.x before
I can do this.
