        src            : LR0.c nullable.c reduce.c reduce.h 

Log message:
        Because useless nonterminals are now kept alive (instead of being
        `destroyed'), we now sometimes examine them, and store information
        related to them.  Hence we need to know their number, and adjust
        memory allocations.
        * src/reduce.c, src/reduce.h (nuseless_nonterminals): No longer
        static.
        * src/LR0.c (allocate_itemsets): The memory allocated to
        `symbol_count' was used for two different purpose: once to count
        the number of occurrences of each symbol, and later reassigned to
        `shift_symbol', containing the symbol that can be shifted from a
        given state.
        Deobfuscate, i.e., allocate, use and free `symbol_count' here
        only, and...
        (new_itemsets): Allocate `shift_symbol' here.
        (allocate_itemsets): symbol_count includes useless nonterminals.
        Make room for them.
        (free_storage): Use `free', not `XFREE', for pointers that cannot
        be null.
