Could I persuade you to make RTL available as a sun .o file?  Given this,
I can relocate the binary to another machine whose processesor is a 68000-
family.  The creation of this .o file can be a bit painful, but would
be worthwhile to me... the question is, would it be for you, too?
There are two methods to create a "portable" .o file:


     1. With all library references resolved.
	This approach has the advantage that all my troubles are reduced to
	worrying about the incompatibilities between sun's system call
	interface and the "other" machine's interface.  It has the disadvantage
	that if you cannot compile and link everything on a sun 3, it will be
	impossible for me to continue because of the floating point/long
	integer library incompatibilities.  This approach takes more time; you
	need a special libc.a that has all of the system calls removed (e.g.
	open, read, write, socket, close, etc.) Then you link using the -r
	option to ld:
		ld -o rtl.obj -r *.o special-libc.a -lX11
	this .o file can be linked again against my own libc.

     2. With all library references unresolved.
	This method has the advantage that any bug fixes to Xlib can be
	achieved simply by relinking with the "fixed" xlib.  It has the
	disadvantage that if the sun has different structure declarations
	for system structures (like stat, timeval), then there are
	more headaches in making the program work.  This method is a
	bit easier: simply link all the rtl-specific .o files together
	using the -r flag and you're done.
		ld -o rtl.obj -r *.o

I will appreciate it if this is within the range of things you are willing
to do, but will understand if it is not.  Please respond either way.

PS
Please note that I am no longer at Project Athena.
