location to be adjusted.
The first function seems to work fine, but there's a problems with the
scope of params causing params to get their knickers in a twist (tangled

Since there is now a proper symbol table, defs are now just references to
memory locations and the symbol table takes care of duplicates.
Also, start using far data for ObjQC structures.
The qfo functions have been stubbed out until I figure out what to do with
object files in the new scheme.
