Put all the functions into a library.  Link the application and the
modules against this library (building only the appA's main() into
the executable).

It was also reported that creating an import library (or stub library)
for the executables functions is sufficient if it is linked in, IIRC it
was the same problem with naim & plugins.  Maybe there are some useful
hints in the naim sources.
