(rule_number): Renamed from rule_number_t.
(struct rule_s): Remove the "rule_s" part; not used.
(rule): Renamed from rule_t.
(rule_filter): Renamed from rule_filter_t.
(ITEM_NUMBER_MAX, ITEM_NUMBER_MIN, RULE_NUMBER_MAX):
Remove; unused.
since this causes problems when __file__ contains character
sequences like "@" that are treated specially by src/scan-skel.l.
Instead, just use the file's basename. This fixes the bug
reported by Martin Mokrejs in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.
POSIX requires. Improve the quality of locations in Bison
diagnostics.
Remove duplicate decl of current_file.
Fix minor promotion problem in templates.
Fix Debian Bug 102878.
(YY_USER_INIT): Initialize scanner_cursor instead
of *loc.
(STEP): Remove. No longer needed, now that adjust_location does
the work. All uses removed.
(scanner_cursor): New var.
(adjust_location): Renamed from extend_location. It now sets
*loc and adjusts the scanner cursor. All uses changed.
Don't bother testing for CR.
(handle_syncline): Remove location arg; now updates scanner cursor.
All callers changed.
(unexpected_end_of_file): Now accepts start boundary of token or
comment, not location. All callers changed. Update scanner cursor,
not the location.
(SC_AFTER_IDENTIFIER): New state.
(context_state): Renamed from c_context. All uses changed.
(id_loc, code_start, token_start): New local vars.
(<INITIAL,SC_AFTER_IDENTIFIER>): New initial context. Move all
processing of Yacc white space and equivalents here.
(<INITIAL>{id}): Save id_loc. Begin state SC_AFTER_IDENTIFIER
instead of returning ID immediately, since we need to search for
a subsequent colon.
(<INITIAL>"'", "\""): Save token_start.
(<INITIAL>"%{", "{", "%%"): Save code_start.
(<SC_AFTER_IDENTIFIER>): New state, looking for a colon.
(<SC_YACC_COMMENT>, <SC_COMMENT>, <SC_LINE_COMMENT>):
BEGIN context_state at end, not INITIAL.
(<SC_ESCAPED_STRING>"\"", <SC_ESCAPED_CHARACTER>"'",
<SC_BRACED_CODE>"}", <SC_PROLOGUE>"%}", <SC_EPILOGUE><<EOF>>):
Return correct token start.
(<SC_BRACED_CODE,SC_PROLOGUE,SC_EPILOGUE>): Save start boundary when
the start of a character, string or multiline comment is found.
(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.
