I hope that's a typo because my gcc with "gcc --version" prints
powerpc-apple-darwin8-gcc-4.0.0 (GCC) 4.0.0 (Apple Computer, inc, build
5026)
And Xcode:
Version 2.2 (Seed)
Xcode IDE: 622.0
Xcode Core: 622.0
ToolSupport: 610.0

That did the trick! :-)
[I noticed that "Deployment Postprocessing" still gives larger files
than "-Wl,-s", compare the sizes
strip (-Wl,-s)
1,518,745 bytes
strip ("Deployment Postprocessing")
1,635,689 bytes]
That's it, about 100 kB larger. Am I stripping to much with -Wl,-s or
can I safely use it in a deployment product instead of "Deployment
Postprocessing"?

I was just curious how this could be, since I supposed dead-code
elimination + stripping would produce even lesser code than just DCE.
But appereantly this is not the case?
Thanks for the help!
