Hi. However, why g++.old-deja/g++.other/builtins9.C does not fail during 
g++ regression testing? This I cannot understand because, to be honest, 
I don't know in detail how those tests are carried out. Perhaps are 
build not link?!? Roger (and Mark) of course meant to link too, but...

Notice, however, that running it -O0 helped us catching this problem ;-)
But I agree that -O2 is much more realistic. Ideally, we should iterate 
over various optmization levels, perhaps...

Ciao, P.
