+       Deprecate %pure-parser and add `%define api.pure'.  Discussed starting
+       at
+       <http://lists.gnu.org/archive/html/bison-patches/2007-09/msg00006.html>.
+       * NEWS (2.3a+): Mention.
+       * data/bison.m4 (b4_pure_if): Don't define it here.
+       * data/c.m4 (b4_identification): Depend on individual skeletons to
+       define b4_pure_flag, b4_push_flag, or b4_pull_flag if they use the
+       values of the %define variables api.pure or api.push_pull.  Define
+       YYPURE, YYPUSH, and YYPULL accordingly.
+       * data/glr.c: Define b4_pure_if based on `%define api.pure' unless
+       glr.cc has already defined b4_pure_flag.
+       * data/push.c: Define b4_pure_if based on `%define api.pure'.
+       Remove YYPUSH and YYPULL since they're back in b4_identification again.
+       * data/yacc.c Define b4_pure_if based on `%define api.pure'.
+       * doc/bison.texinfo (Pure Decl): Update.
+       (Push Decl): Update.
+       (Decl Summary): Add api.pure to %define entry.
+       In %pure-parser entry, say it's deprecated and reference %define.
+       (Pure Calling): Update.
+       (Error Reporting): Update.
+       (C++ Scanner Interface): Update.
+       (How Can I Reset the Parser): Update.
+       (Table of Symbols): In %pure-parser entry, say it's deprecated and
+       reference %define.
+       * src/getargs.c (pure_parser): Remove global variable.
+       * src/getargs.h (pure_parser): Remove extern.
+       * src/output.c (prepare): Don't define pure_flag muscle.
+       * src/parse-gram.y (prologue_declaration): Implement %pure-parser as a
+       wrapper around `%define api.pure'.
+       * tests/calc.at (Simple LALR Calculator): Update.
+       (Simple GLR Calculator): Update.
+       * tests/cxx-type.at (GLR: Resolve ambiguity, pure, no locations):
+       Update.
+       (GLR: Resolve ambiguity, pure, locations): Update.
+       (GLR: Merge conflicting parses, pure, no locations): Update.
+       (GLR: Merge conflicting parses, pure, locations): Update.
+       * tests/glr-regression.at (Uninitialized location when reporting
+       ambiguity): Update
+       * tests/input.at (Unused %define api.pure): New test case.
+       * tests/local.at (_AT_BISON_OPTION_PUSHDEFS): Update definition for
+       AT_PURE_IF and AT_PURE_AND_LOC_IF.
+       * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Update.
