As I sent this message yesterday, but it seems the message lost somewhere.
I send it again.

As I do not have running NetBSD machines and use FreeBSD, I hope hpcmips binaries
can be cross-compiled on a FreeBSD machine.

At first, I tried to compile the hpcmips build on FreeBSD directly
but it faied because the build architectures between FreeBSD and NetBSD are
different so much, so I decided to use NetBSD runtime binaries in a chrooted
enviroment on FreeBSD(4.1).

Though I have not succeed in building hpcmips `make build' yet, a step toward
hpcmips-cross-compiling on FreeBSD is found. Any help is appreciated.

here is a simple procedual description which I succeed so far.
(1) Get NetBSD binaries. I used 1.5_ALPHA2 snapshot on ftp://ftp.netbsd.org/
    I downloaded with this script. And unpack the binaries to some directory.
    Suppose you put the binaries in /NetBSD. (The directory resides in
    a FreeBSD machine.)
--- begin script
#!/bin/sh
# runs on FreeBSD
MACHINE=i386
BINARY_URL="ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-1.5_ALPHA2/$MACHINE/binary/sets"

b="base.tgz comp.tgz etc.tgz misc.tgz text.tgz"
for a in $b; do
        fetch $BINARY_URL/$a
done
--- end script
(2) Emulate Netbsd's system calls which are not present in FreeBSD(4.1).
    As I do not know much about kernel emulation in FreeBSD, I changed
    kern/init_sysent.c directly. I used FreeBSD 4.1 compiled on our site.
    Make kernel, make kernel-install and then reboot.
    CAUTION: This change may damege your system, use it with your own risk.
    Here is the diff.

(3) Chroot to /NetBSD. We are in the (pseudo) NetBSD enviroment on FreeBSD.
    It seems most programs work, as far as I know.

(4) Install ftp://ftp.netbsd.org/pub/NetBSD/arch/hpcmips/cross/i386-hpcmips/
    files and slitly changed the hpcmips-make and did `hpcmips-make build'.
    It failed with the following error message. The point is _ns`something'
