How about the following instead?  I'd rather use a simpler regexp if
it works.  Can you please verify that this works on the broken
implementation?  Thanks.

$ expr 'Xpowerpc-apple-darwin8.1.0' : '.*-\(.*\)'
darwin8.1.0
$ expr 'Xpowerpc-apple-darwin8.1.0' : '.*-\(.*\)-.*'
apple
$ expr 'Xpowerpc-apple-darwin8.1.0' : 'X\(.*\)-.*-'
powerpc
