location that is not defined. This results in garbage, and that affects Bison's own parser. Therefore we need (i) to extend Bison to support a means to initialize this location, and (ii) to use this CVS Bison to fix CVS Bison's parser. * src/reader.h, reader.c (epilogue_augment): Remove, replace with... * src/muscle_tab.h, src/muscle_tab.c (muscle_code_grow): this. * src/parse-gram.y: Adjust. (%initial-action): New. (%error-verbose): Since we require CVS Bison, there is no reason not to use it. * src/scan-gram.l: Adjust. * src/Makefile.am (YACC): New, to make sure we use our own parser. * data/yacc.c (yyparse): Use b4_initial_action.
