(STRUNIQ_EQ, struniq_assert, struniq_assert_p): New. Use struniq for symbols. * src/symtab.h (symbol_t): The tag member is a struniq. (symbol_type_set): Adjust. * src/symtab.c (symbol_new): Takes a struniq. (symbol_free): Don't free the tag member. (hash_compare_symbol_t, hash_symbol_t): Rename as... (hash_compare_symbol, hash_symbol): these. Use the fact that tags as struniqs. (symbol_get): Use struniq_new. * src/symlist.h, src/symlist.c (symbol_list_n_type_name_get): Returns a strniq. * src/reader.h (merger_list, grammar_currentmerge_set): The name and type members are struniqs. * src/reader.c (get_merge_function) (grammar_current_rule_merge_set): Adjust. (TYPE, current_type): Are struniq. Use struniq for file names. * src/files.h, src/files.c (infile): Split into... (grammar_file, current_file): these. * src/scan-gram.c (YY_USER_INIT, handle_syncline): Adjust. * src/reduce.c (reduce_print): Likewise. * src/getargs.c (getargs): Likewise. * src/complain.h, src/complain.c: Likewise. * src/main.c (main): Call struniqs_new early enough to use it for file names. Don't free the input file name.
