It needs to be defined if the code being compiled was generated using
the high-level data representation.  For the csharp grade, it always
needs to be defined since the C# backend always uses that
representation. 
(The old IL backend allowed either low-level or high-level
representations to be used and the csharp grade shares some C# foreign
procs with it.)
