   Here's a very practical (as opposed to pedantically correct) solution.

   Include the following ".h" file in your yacc file.
   Replace all <unique_name_here> with whatever name you wish.
   Call to parser becomes <unique_name_here>_yyparse()

--- yacc_unique.h ---

#define yyback		<unique_name_here>_yyback

--- yacc_unique.h ---

And best of all, no `sed' scripts.
