Try making CONSTANT_ADDRESS_P reject the value.

Though it still isn't clear why you are getting relocation errors.  If 
addresses wrap around at segment boundaries, then this should just work 
fine.  a-40 gets converted into a very large positive segment offset 
that then wraps around back to a when 40 is added to it.  Perhaps the 
assembler/linker need some work to handle this correctly.
