/*
Name
  tcprs_rt.cpp - stubs for parser functions not needed in run-time 
Function
  Interpreters that include "eval()" functionality require a portion of the
  compiler, including code body and expression compilation.  This module
  provides stubs for functions that aren't needed for interpreter
  configurations, but which are referenced from the parts of the compiler we
  do need, to resolve symbols at link time.  Many of these stubs are simply
  never called in interpreter builds, because the conditions that would
  trigger their invocation can't occur; others just need to provide defaults
  or other simplified functionality when called; others generate errors,
  because the functionality they provide is specifically not supported in
  interpreter builds.
