Um. You don't have their "real" cc then, just the brain-dead
non-optimizing one. IMHO that's only fit for bootstrapping gcc ;-).
However, my experiences with it were on PA-RISC, which really
desperately needs an optimizing compiler to perform decently.
I don't know what the hit would be like on IA64.
You could try manually repairing gcc's copy of sys/types.h by adding
the stuff it's missing compared to /usr/include. I'm not sure how
many other discrepancies there are and which if any might be critical.
