r-r.rep

Object-Oriented Programming With ANSI-C这本书中的源代码!找了很久

// differences from r.rep:
//	there is no superclass header to include
//	we generate `root and `metaroot at % root in `{dcl, because
//	we explicitely insert the `root `{%- into struct `metaroot
//
% -r			// implement -r option for root class

#  ifndef  `class _r `n
#  define  `class _r `n `n
