/** comments are treated specially (they're JavaDoc comments, and 
ANTLR tries to attach them to the generated methods).  As such, 
they're only really valid in a place where ANTLR is about to 
generate a method or class.  Before rules and grammar declarations 
are just such places; before a members block is not.

If you want to put in an arbitrary comment, use /* instead of /**.
