+
+       Add maintainer-push-check to run maintainer-check using push parsing in
+       place of pull parsing where available.
+       * Makefile.am (maintainer-push-check): New.
+       * data/bison.m4 (b4_use_push_for_pull_if): New.
+       * data/push.c: Redefine b4_push_if and b4_use_push_for_pull_if
+       appropriately based on their existing values.
+       (yypush_parse): Don't print push-parser-specific diagnostics if push
+       parsing is being used in place of pull parsing.
+       * data/yacc.c: If push parsing should replace pull parsing, redirect to
+       push.c.
+       * src/output.c (prepare): Check BISON_USE_PUSH_FOR_PULL environment
+       variable, and insert b4_use_push_for_pull_flag into muscles.
+       * tests/Makefile.am (maintainer-push-check): New.

+
+       * data/push.c (yypush_parse): Set yynew = 1 at the end of a parse
+       (whether successful or failed) so that yypush_parse can be invoked
+       again to start a new parse using the same yypstate.
+       * tests/torture.at (AT_DATA_STACK_TORTURE): For push mode, extend to
+       check multiple yypull_parse invocations on the same yypstate.  For pull
+       mode, extend to check multiple yyparse invocations.
+       (Exploding the Stack Size with Alloca): Extend to try with
+       %push-pull-parser.
+       (Exploding the Stack Size with Malloc): Likewise.
+
+       * tests/calc.at (Simple LALR Calculator): Don't specify
+       %skeleton "push.c" since %push-pull-parser implies that now.
+       * tests/headers.at (export YYLTYPE): Don't check for the push
+       declarations.  Otherwise, this test case can't be used to see if push
+       mode can truly emulate pull mode.
+       * tests/input.at (Torturing the Scanner): Likewise.
+       * tests/local.at (AT_YACC_OR_PUSH_IF, AT_PUSH_IF): Remove.
+       (AT_YYERROR_SEES_LOC_IF): Rather than AT_YACC_OR_PUSH_IF, use
+       AT_YACC_IF, which now includes the case of push mode since %skeleton
+       need not be used for push mode.  This will be more intuitive once
+       push.c is renamed to yacc.c.

        For push mode, convert yyparse from a macro to a function, invoke yylex
