I had the same problem with my Oregon C++ compiler.  In my case, the
compiler was writing out object files in 512 byte blocks (for efficiency).
At the end of the object code, the compiler just zero filled to the end of
the 512 byte block.  New to the SunOS 4.1 object file format there is some
additional junk after the symbol table (possibly to support a browser or
something, maybe?).  Anyway, this additional info is protected by a magic
number, hence the error message "bad secondary magic number".  In my case,
the solution was very simple: all I had to do was to write a short program
to truncate the object file at the end of the symbol table.  If you would
like, I could send the code.  Note that I also had to tear apart the
libraries, truncate the object files therein, and rebuild them.  If you
look at your object files (I used bpatch) and see a lot of binary zeros at
the end, I would think that that is your problem as well.  Hope this
helps.
