FORGET trying to use coff encapsulation.  The robotussin stuff is 
a nightmare, and  despite FSF claims to the contrary, they don't really
support it.

Much simpler, and easier to use (although also not supported by FSF)
is the set of coff patches available in the file:
	tut.cis.ohio-state.edu:/pub/gnu/coff/gnu-coff.tar.Z

These patches add an additional output stage to an otherwise essentially
unmodified "gas" causing it to produce coff output files which can be used
with the native loader.

The debug info is dbx format rather than sdb format, however (encoded as
"stabs" - string-table debug info).  Thus, native tools will see the debug
symbols as plain non-debug symbols. 

A set of patches for gdb are also included.  Aside from some bug
fixes, these patches add a routine that converts the dbx debug info in
coff files into gdb's internal format (for those familiar with gdb
internals, the routine gets called from "fill_symbuf()".  The
debugging capabilities are significantly better than they would be
with an sdb style encoding of debug information.

Except for the gas 1.36, gcc, and gdb sources themselves, the patch set
contains everything you need for an ESIX system, including appropriate
config files for gcc and gdb.
