+       Replace `%push-parser' and `%push-pull-parser' with
+       `%define push_pull "push"' and `%define push_pull "both"'.
+       `%define push_pull "pull"' is the default.
+       * doc/bison.texinfo (Push Decl, Push Parser Function,
+       Pull Parser Function, Parser Create Function, Parser Delete Function):
+       Update declarations.
+       (Decl Summary, Table of Symbols): Replace %push-parser and
+       %push-pull-parser entries with a %define push_pull entry.
+       * data/bison.m4 (b4_percent_define_check_values): New macro.
+       (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these
+       definitions...
+       * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp
+       definitions...
+       * data/push.c: ... to here and compute them from the value of the
+       %define variable push_pull.
+       * data/c-skel.m4: Instead of choosing the push.c skeleton for push
+       parsing requests here...
+       * data/yacc.c: ... hack this to switch to push.c any time
+       b4_use_push_pull_flag or the %define variable push_pull is set.  This
+       will go away when we mv push.c yacc.c.
+       * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that
+       push parsing is not supported since unused %define variables are
+       reported anyway.
+       * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove.
+       * src/muscle_tab.h (muscle_percent_define_check_values): Update
+       comments for consistency with b4_percent_define_check_values.
+       * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag
+       muscles.
+       * src/parse-gram.y (PERCENT_PUSH_PARSER, PERCENT_PUSH_PULL_PARSER):
+       Remove.
+       (prologue_declaration): Remove %push-parser and %push-pull-parser
+       rules.
+       * src/scan-gram.l (%push-parser, %push-pull-parser): Remove rules.
+       * tests/calc.at: Update declarations.
+       * tests/input.at (%define enum variables): New test case.
+       * tests/push.at (Push Parsing: Memory Leak for Early Deletion): Update
+       declaration.
+       (Push Parsing: Multiple impure instances): Update declaration.
+       (Push Parsing: Unsupported Skeletons): New test case.
+       * tests/torture.at (Exploding the Stack Size with Alloca): Update
+       declaration.
+       (Exploding the Stack Size with Malloc): Update declaration.
