Isn't there too many "end"? grammar of racc file is changed in v0.10.
Racc does not use '%' mark, while yacc uses huge number of '%' marks..
Try "racc -v xxxx.y". It causes producing racc's internal log file, xxxx.output.
Try "racc -g xxxx.y". This command let racc generate "debugging parser". Then set @yydebug=true in your parser. It produces a working log of your parser.
