/* 
 * Forward declarations for types used in YYSTYPE.
 *
 * 
 * FYI: when a C/C++ program only uses pointers to a type, you do not
 * need the complete definition of the type, but rather just one of
 * these forward declarations.  By not including the complete
 * definitions, it reduces dependencies between separately compiled
 * units: and also is sometimes completely necessary to avoid circular
 * dependencies.
