Did your actual system install on your Pentium D is in 64 bits ?

In that case he should be cross-compiling with a CHOST set for the
PentiumD, not so?

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.
Hi Mark,
I actually wasn't planning on using 64bit anyway
I'm wondering if I should set my CFLAGS to -march=x86-32 or leave it as
-march=pentium4? Are they essentially the same? I already took your
previous suggestion and enabled vSMP support, though I haven't moved the
drive to it's new home as of yet.
