(boundary): New type.
(location_t): Use it. This allows locations to span file boundaries.
All member uses changed: file -> start.file or end.file (as needed),
first_line -> start.line, first_column -> start.column,
last_line -> end.line, last_column -> end.column.
(equal_boundaries): New function.
(LOCATION_RESET, LOCATION_STEP): Remove.
(LOCATION_PRINT): Remove. All callers changed to use location_print.
(empty_location): Now const.
(location_print): New decl.
(empty_location): Now const.
(location_print): New function. Follow the recommendation of the
GNU Coding Standards for locations that span file boundaries.
(STRING_GROW): Renamed from YY_OBS_GROW. All uses changed.
(STRING_FINISH): Renamed from YY_OBS_FINISH. All uses changed.
(STRING_FREE): Renamed from YY_OBS_FREE. All uses changed.
All uses changed.
(YYPARSE_PARAM, YYLEX_PARAM, yycontrol): Remove. All uses changed.
The name "yycontrol" violates the name space rules, and this stuff
wasn't being used anyway.
(input): Remove action; this stuff wasn't being used.
(gram_error): Rename local variable yylloc -> loc.

support (used to be M4 macros).

Add several files that autoreconf may bring in during
bootstrap.
cannot be NULL, not XFREE.

* src/location.h (LOCATION_PRINT): If first_line is 0, just issue
the file name.
Restore.
* src/scan-gram.l (last_string): Is global to the file, not to
yylex.
* src/parse-gram.y (input): Don't append the epilogue here,
(epilogue.opt): do it here, and free the scanner's obstack.
* src/reader.c (epilogue_set): Rename as...
(epilogue_augment): this.
* data/c.m4 (b4_epilogue): Defaults to empty.
(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/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.
type_name are properly removed.
Don't use XFREE to free items that cannot be NULL.
* src/struniq.h, src/struniq.c: New.
* src/main.c (main): Initialize/free struniqs.
* src/parse-gram.y (%union): Add astruniq member.
(yyprint): Adjust.
* src/scan-gram.l (<{tag}>): Return a struniq.
Free the obstack bit that used to store it.
