NOt quite sure when or how this broke.  But ...

This is related to something I'm working on right now.  Basically,
there isn't any really clean way to report errors at code generation
time, and this error isn't caught before code generation time.  So
I'm re-doing the structure of the compiler a bit to improve this.
