If both are HEADs of CVS, I only had to add freebsd-7 and -x86_64-*-freebsd*) +amd64-*-freebsd* | x86_64-*-freebsd*) support into two files in the NetBSD distribution of gcc to make it compile, but other than that it works (I use my 7-current amd64 box dailyto cross-build NetBSD-current for a MIPS-based SoC). > I expect it's pretty different. ru@ did a lot of work on > cross-building FreeBSD though, and he had a fairly detailed list > of known differences between cross-built and native builds.

I've been able to reduce it to the length of 1, and for some time now, I use my fastest box (amd64) to cross-build and cross-install worlds and kernels for other architecture machines in my home network (i386, alpha, and until recently sparc64).
