+
+       * data/yacc.c (yy_reduce_print): Omit trailing white space in
+       generated source code.  Problem reported by Frans Englich in
+       <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00049.html>.

+
+       * Makefile.maint (gzip_rsyncable, GZIP_ENV): Compute within the
+       shell, not within 'make', so that 'make' by an ordinary builder
+       (using GNU make) does not worry about configuring gzip.  This also
+       works around a bug reported independently by Keith Thompson and by
+       Georg Schwarz, whereby gzip 1.2.4 --help would output usage on
+       stderr rather than stdout, messing up the build logs.

+
+       * data/yacc.c (yyparse): Wrap the final return from yyparse inside YYID
+       to make sure that YYID will never be unused.  This fixes a 'make
+       maintainer-check' failure caused by the recent changes to the 'Trivial
+       grammars' test case, which caused g++ 4.1.0 to complain that YYID was
+       not used.
+       * data/glr.c (yyparse): Wrap yyparse's return inside YYID just in case.

+
+       * data/glr.c (yyresolveLocations): Remove bogus YYASSERT that the
+       state before an empty RHS is always resolved here.  Only the location
+       of that state is guaranteed to be resolved, and that's enough.  This
+       fixes the remaining bug reported by Derek M. Jones in
+       <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+       * tests/glr-regression.at (Uninitialized location when reporting
+       ambiguity): Test the above case.
+       Also, the embedded comments in this test case claim it checks the case
+       of an empty RHS that has inherited the initial location.  However, the
+       corresponding LHS was already resolved, so yyresolveLocations didn't
+       actually have reason to modify it.  Fix this by forcing
+       nondeterministic operation at the beginning of the parse.

+
+       * data/c.m4 (b4_yy_symbol_print_generate):
+       (b4_yy_symbol_print_generate): Use 'YYSTYPE const' rather than
+       'const YYSTYPE', and similarly for YYLTYPE.  This fixes one
+       of the bugs reported today by Derek M Jones in
+       <http://lists.gnu.org/archive/html/bug-bison/2006-05/msg00027.html>.
+       * doc/bison.texinfo (Value Type): Document that YYSTYPE must be
+       defined to be a type name without parens or brackets.
+       (Location Type): Similarly for YYLTYPE.
+       * tests/regression.at (Trivial grammars): Put in a test for this
+       bug that will be caught by 'make maintainer-check' (though not,
+       alas, by 'make check' unless your compiler is picky).
