+ doc: discuss named references after locations.
+ Reported by Hans Aberg at
+ <http://lists.gnu.org/archive/html/bug-bison/2011-05/msg00008.html>.
+ * NEWS (2.5.1): Document.
+ * doc/bison.texinfo (Named References): Because it discusses
+ locations in addition to semantic values, move this subsection out
+ of the section `Defining Language Semantics', where locations have
+ not yet been introduced, to be a new section after the following
+ section, `Tracking Locations'.

+
+ Don't use IF_LINT in Bison sources.
+ It creates unnecessary differences between the sources that Bison
+ maintainers build and test (given that maintainers normally
+ configure with --enable-gcc-warnings) and the sources that Bison
+ users build. Instead, use PACIFY_CC, which doesn't. This change
+ fixes compiler warnings reported by Tys Lefering at
+ <http://lists.gnu.org/archive/html/bison-patches/2011-05/msg00004.html>.
+ * configure.ac: Don't AC_DEFINE lint regardless of the configure
+ options. This change affects imported gnulib sources, where
+ IF_LINT still appears and depends on lint.
+ * src/scan-gram.l, src/scan-skel.l: Replace uses of IF_LINT with
+ PACIFY_CC.
+ * src/system.h (IF_LINT): Remove cpp macro.
+ (PACIFY_CC): New cpp macro.
