+
+       * src/symtab.h, src/symtab.c (symbol_t): printer and
+       printer_location are new members.
+       (symbol_printer_set): New.
+       * src/parse-gram.y (PERCENT_PRINTER): New token.
+       Handle its associated rule.
+       * src/scan-gram.l: Adjust.
+       (handle_destructor_at, handle_destructor_dollar): Rename as...
+       (handle_symbol_code_at, handle_symbol_code_dollar): these.
+       * src/output.c (symbol_printers_output): New.
+       (output_skeleton): Call it.
+       * data/bison.simple (yysymprint): New.  Cannot be named yyprint
+       since there are already many grammar files with a user `yyprint'.
+       Replace the calls to YYPRINT to calls to yysymprint.
+       * tests/calc.at: Adjust.
+       * tests/torture.at (AT_DATA_STACK_TORTURE): Remove YYPRINT: it was
+       taking advantage of parser very internal details (stack size!).

+
+       * src/scan-gram.l: Complete the scanner with the missing patterns
+       to pacify Flex.
+       Use `quote' and `symbol_tag_get' where appropriate.
+

+
+       * tests/actions.at (Destructors): Augment to test locations.
+       * data/bison.simple (yydestructor): Pass it the current location
+       if locations are enabled.
+       Prototype only when __STDC__ or C++.
+       Change the argument names to move into the yy name space: there is
+       user code here.

+
+       * data/bison.simple (b4_pure_if): New.
+       Use it instead of #ifdef YYPURE.

+
+       * data/bison.simple (b4_location_if): New.
+       Use it instead of #ifdef YYLSP_NEEDED.
+
+2002-06-19  Akim Demaille  <akim@epita.fr>
+
+       Prepare @$ in %destructor, but currently don't bind it in the
+       skeleton, as %location use is not cleaned up yet.
+
+       * src/scan-gram.l (handle_dollar, handle_destructor_at)
+       (handle_action_at): New.
+       (handle_at, handle_action_dollar, handle_destructor_dollar): Take
+       a braced_code_t and a location as additional arguments.
+       (handle_destructor_dollar): Instead of requiring `b4_eval', just
+       unquote one when outputting `b4_dollar_dollar'.
+       Adjust callers.
+       * data/bison.simple (b4_eval): Remove.
+       (b4_symbol_destructor): Adjust.
+       * tests/input.at (Invalid @n): Adjust.
+
+2002-06-19  Zack Weinberg  <zack@codesourcery.com>
+
+       * doc/bison.texinfo: Document ability to have multiple
+       prologue sections.
+
+2002-06-18  Akim Demaille  <akim@epita.fr>
+
+       * src/files.c (compute_base_names): When computing the output file
+       names from the input file name, strip the directory part.
