+       Port to GCC 2.95.  First two problems reported by Michael Deutschmann in
+       <http://lists.gnu.org/archive/html/bug-bison/2006-09/msg00018.html>.
+
+       * src/parse-gram.y (symbol_declaration): Don't put statements
+       before declarations; it's not portable to C89.
+       * src/scan-code.l (handle_action_at): Likewise.
+
+       * src/scan-code.l: Always initialize braces_level; the old code
+       left it uninitialized and therefore had undefined behavior.
+
+       Don't attempt to redefine 'assert', since it runs afoul of
+       systems where standard headers (mistakenly) include <assert.h>.
+       Instead, define and use our own alternative, called 'aver'.
+       * src/reader.c: Don't include assert.h, since we no longer
+       use assert.
+       * src/scan-code.l: Likewise.
+       * src/system.h (assert): Remove, replacing with....
+       (aver): New function, taking a bool arg.  All uses changed.
+       * src/tables.c (pack_vector): Ensure that aver arg is bool,
+       not merely an integer.

+
+       * data/Makefile.am (dist_pkgdata_DATA): Add push.c.
+       * data/c.m4 (YYPUSH): New.
+       (b4_push_if): New macro.  Use it instead of #ifdef YYPUSH.
+       * src/getargs.c (push_parser): New var.
+       * src/getargs.h (push_parser): New declaration.
+       * src/output.c (prepare): Add macro insertion of `push_flag'.
+       * src/parse-gram.y (PERCENT_PUSH_PARSER): New token.
+       (prologue_declaration): Parse %push-parser.
+       * src/scan-gram.l: Scan new PERCENT_PUSH_PARSER token.
+       * tests/calc.at (_AT_CHECK_CALC_ERROR): Add "Return" and "Now" to
+       list of removed lines from the traces observed.
+       (AT_CHECK_CALC_LALR): Added push parser tests.
+
 2006-09-13  Paul Eggert  <eggert@cs.ucla.edu>
 
+       * NEWS: Version 2.3a.
+       * configure.ac (AC_INIT): Likewise.
+
        * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Remove
        "#define YYSTYPE int" that caused "make maintainer-check" to fail
        due to header ordering dependencies.  I don't know why the #define
