I cannot know for sure what the problem is because I am no working with your 
code and build environment.

My guesses and ideas are:

  The fixup problem might stem from the -a2 compile option.
  Double check the reasons your need that and consider
  implementing it in a manner which encases any structures
  that are the issue instead of globally forcing it.

  bcc @options.cfg etc
     really should be
  bcc +options.cfg etc

  -RT- and -x- are used but noehL.lib is not used.  Add noehl
  to the library list before any other compiler-supplied libraries.
  This effects size and performance and is not a source of the
  problems you report.

  I would like to see you try a build without -Od and without
  -1 (independent items, no intended implication that they
  have a special effect when combined)  Note that there
  are -O1 and -O2 alternatives to select from (also note that
  I used -Od for years and am not saying it is a guaranteed
  problem)

  I don't remember offhand all the details of -dc, -Ff=2000 and
  -mm!  Double check them and why they are used.  Take care
  to validate the reason the number given to -Ff is 2000

As for the multiple definition errors, what you show suggests that the way 
you are providing the library is actually as a set of object files and not 
as a *.lib file.  Any duplicate symbols found in object files explicitly 
given to the linker will be and should be an error.

It might be a good idea to create a library containing the object files that 
are built outside of the project.  Maybe something like this might work 
better (just typed in - beware of typos).  Don't fall back on NIH.  Try it, 
defer complaining about it until you see the results :-)
