    It depends on what's your FreeBSD and NetBSD versions are. 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'm sure I reported it to the current@ list a while back. 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).

    Cheers,
