FreeBSD-4 executables on 7.x/amd64

[Mikhail Teterin]

Hello!

I have a 7.0 system (amd64) and am trying to run a FreeBSD-4 executable.
It dies on startup with "bad system call". The core shows, that it is
simply trying to mmap something.

I have the following COMPAT-options enabled in my kernel:

options         COMPAT_43               # Needed by COMPAT_LINUX32
options         COMPAT_IA32             # Compatible with i386 binaries
options         COMPAT_FREEBSD4         # Compatible with FreeBSD4
options         COMPAT_LINUX32          # Compatible with i386 linux binaries

Should not that be enough? Thanks!
