If you have the "default" value, it should be the default. So the base 
properties should have <object-model>default. And...

You would then need to add handling for <object-model>default to the 
toolset:

flags tru64cxx65 C++FLAGS <object-model>default : -model ansi ;
flags tru64cxx65 LINKFLAGS <object-model>default : -model ansi ;
