Then we would have once per week a new version number. It happens quite 
often that the a one day old cvs version can't compile the current cvs 
compiler because either of a new feature or simply a bug in the older 
compiler. That's why we have the very simple rule: start building a new 
compiler with the lastest stable release.

I added these conditions to allow bootstrapping on PowerPC. Because 
there is no 1.0.10-ppc is available, we can use only 1.9.2.
