`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.
(reduce_output): This.
Output to OUT, passed as argument, instead of output_obstack.
(dump_grammar): Likewise.
(reduce_free): New.
Also free V1.
(reduce_grammar): No longer call reduce_output, since...
* src/print.c (print_results): do it.
* src/main.c (main): Call reduce_free;
