Things to beware of on the DEC3100:

1) There is a bug in nlist(). It eats about 250K per call.  This is a
problem only for routines not in the load list.
2) The object format is COFF, so there is no dynamic loading.
3) There are no initial underscores in loader names
4) You get lots of warning messages about illegal pointer combinations
from declarations of the routine signal -- ignore them.
5) The optimizer in the f77 compiler dies with an internal error when
compiling the routine $F/mstree/mstree.r.  Don't use
the optimizer on this routine.

Execute the following commands from $SHOME/machines/dec3100: 

	rm -f $P/natst.r
	cp natst.C $P/natst.C
	rm -f $QPE/mips_na.c
	cp mips_na.c $QPE/mips_na.c

Make the following changes to $C/makehead:

	CFLAGS=-O2 
	FFLAGS=-O2

Make the following changes to $QPE/Makefile, and $QPE/S_makefile:

	CCFLAGS=-O2 -Olimit 2000
	FFLAGS=-O2
	UNDEF=-u ld_init -u Sfun

Add mips_na.o to the list of files named MAIN in $QPE/Makefile.

Change $QPE/sys_funs.c so that the lines that were
#ifdef ATT_UNIX
now read
#if defined(ATT_UNIX) || defined(mips)
in routine get_entry and just before the routine dyn_load.
