Andrew,
Thanks but that does not seem to be the silver bullet.

I'm not entirely sure this is what you want, but you might try the -u 
switch.  It's a linker option that is used to "Pretend the symbol is 
undefined, to force linking of library modules to define it.  You can 
use -u multiple times with different symbols to force loading of 
additional library modules."
