[ ... long sad story about incompatibility of object formats follows... ]

One possible way that you might be able to solve one or more of your
problems (and still avoid having to run AWK over assembly files) is to
see if you can perhaps use either the GNU assembler or the GNU linker
or both. These are a.out (BSD format) oriented tools however, so if you
gotta work with some other object format, they won't help much.

Of course you might also want to consider using the GNU C compiler as well.

In case you don't know, all of these hunks of software can be had for free.
Professional level support (if you need it) costs extra however, but it
can be had at reasonable rates from several sources on a coast near you.
