+
+       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
+       was there.
+
        Fix glr.cc and lalr1.cc's use of YYDEBUG so that there's zero
        runtime cost when YYDEBUG is not defined, and so that some tests
        that used to fail now work.  Problem and initial suggestion by
