+       * doc/bison.texinfo (Introduction): Mention GLR and C++ as on the web
+       page.  Say "you can use it" not "you may use it" as on the web page;
+       we're describing capabilities not granting permission.

+       * data/glr.c (yyresolveLocations): Rename local variables to avoid
+       shadowing warnings.  Use usual patter for iterating through RHS.
+       * tests/glr-regression.at
+       (Uninitialized location when reporting ambiguity):
+       Modify yylex so that it uses its argument, rather than trying
+       to rely on ARGSUSED (which doesn't work for gcc with warnings).
+       const char -> char const.
+
+       * tests/Makefile.am ($(srcdir)/package.m4, maintainer-check-valgrind):
+       Don't use tabs inside commands; it messes up 'ps'.
+       Problem reported by twlevo.

+       * doc/bison.texinfo (Default Action for Locations): Note
+       YYLLOC_DEFAULT's usage for ambiguity locations.

        Avoid memory leaks by not invoking longjmp in yyreportAmbiguity.
