                     23:    a BSD 4.3 based operating system, but it runs svr4 ELF format object
                     24:    files and it somehow puts BSD stabs records into the ELF files for
                     25:    symbolic debug information.  It also seems to use the assembler from
                     26:    the svr4 reference port, but that assembler has probably been hacked
                     27:    slightly to allow the BSD stabs to be smuggled in.

                     29:    Given that we need to use svr4-style pseudo-ops, and given that the
                     30:    target object file format is ELF, we just include "i860v4.h" here so
                     31:    as to pick-up a set of defines appropriate for for an svr4/ELF target
