It has been a very long time since I did this, and I may not remember
correctly, but I believe that COMPAT_43 is needed on NetBSD/i386 to run
BSDI binaries.  I remember using the BSDI Netscape 3.x binary back in
the day and I think it was required.

FreeBSD does too... net2 was closer to 4.3 system calls for many things than 4.4.
