`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.
