Hi!

I don't know what I did, maybe some things I had to add to the build
systems, who knows, but it seems to work now.  I can tell for sure it
works on PowerPC and PowerPC64.  I still have problems to get the whole
thing built on Alpha, which is also a floating point problem, but that's
another story...
