Hello,

marco@amisa.iss.infn.it discovered that NetBSD/Amiga 1.3.1 and 1.3.2 do not
handle SunOS/Sun3 executables correctly (even with COMPAT_SUNOS).

The reason is, that a change to sys/arch/amiga/amiga/machdep.c was pulled
up to the 1.3.1 branch by mistake (it would need the corresponding change in 
sys/kern/exec_conf.c to work).

Until 1.3.3 or 1.4 are out, I suggest that you apply the following diff to your
kernel sources and rebuild, if you intend to run SunOS/Sun3 binaries.

Regards,
	Ignatios Souvatzis

Starting from 1.3.1, a change to the function cpu_exec_aout_makecmds in
/sys/arch/amiga/amiga/machdep.c prevents old 68020/sun3 binaries to work with
NetBSD (well, at least the one I use, the algebraic manipulator Schoonschip).
Here is the reverse patch, just in case you need it.
  Ciao. Marco
