You can enable -mcpu=G5 to make use of the 64-bit registers and such, the pointers are still 32-bits, which means that ocaml words will still be 32 bits. I don't know what Apple's plans are as far as 64-bit support in the OS. PPC linux runs native 64-bit on the G5, but it isn't all that stable, yet. Dave
