Ron it sounds like you have an idea in mind, could you elaborate.  

Currently all I am computing are things that the linker needs to deal
with.  The selection of addresses of specific files.  

The ASSERT is especially useful as it turns a very mysterious error
message into something readable and comprehensible.  It is weird
that you have to assign ASSERT to a variable to have the declaration
work in nested linker scripts but hey it works.
