In that case he should be cross-compiling with a CHOST set for the PentiumD, not so? alan -- gentoo-user@gentoo.org mailing list
Yes, he can do so, but he won't be able to test run his apps. And judging from my experience there isn't much difference between apps compiled for x86-32 or x86-64, however compiling the kernel for right cpu speed up things, especially multithreaded.
