Problems building a mips cross compiler

[Soren Dayton]

Hello

I am having trouble building a mips cross compiler.  In particular, I am 
building from sparc-sun-solaris2.5.1 to decstation-ultrix for the nachos 
simulated operating system.  Here is my config.status file:

#!/bin/sh
# This file was generated automatically by configure.  Do not edit.
# This directory was configured as follows:
/stage/languages/local/gcc/egcs-1.0.2/configure --host=sparc-sun-solaris2.5.1 --
prefix=/usr/local/classes/current/CS230/01 --target=decstation-ultrix --norecurs
ion
# using "/stage/languages/local/gcc/egcs-1.0.2/config/mh-solaris"


so.  The problem that I am having is in the:

	#include "mips/a.out.h"

that appears in gcc/mips-tfile.c and the problem is that there is no
such file.  Should I be snarfing it from some machine?  It seems that I
could not build a cross compiler without this file, but I see no
instructions about where to find this file.

Thanks

PS: I was not sure if I am supposed to be on this list or not.  I really 
know very little about compilers, so I do not think that I could
contribute much, but if I should be, please tell me.
