+ 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.

+
+ Fix precedence for end token.
+ Since Bison 2.3b, which restored the ability of precedence

+ doc: clean up naming of various Bison files.
+ The Bison manual's names for various files associated with a Bison

+ traditional in the Bison manual, and Bison has other input
+ files (skeletons). Second, it chooses "parser implementation
+ file" over names like "parser file", "parser source file", "parser
+ source code file", and "parser output file". The new name makes
+ it clearer where Bison generates the main parser implementation,
+ and it is easily distinguishable from "parser header file".

+ doc: give credit to more of Bison's developers.
+ * doc/bison.texinfo (Introduction): Don't imply that only Robert
+ Corbett, Richard Stallman, and Wilfred Hansen have contributed to
+ Bison. However, I don't have time to write a full history, so
+ just point readers to THANKS and ChangeLog.

+ doc: document experimental features better.
+ * doc/bison.texinfo (Introduction): Say that IELR(1) and canonical
+ LR(1) are experimental. Mention Java. Normally experimental
+ features probably shouldn't be mentioned in the introduction.
+ However, if Bison's limitations to LALR(1), C, and C++ are so
+ important that they should be mentioned here, then it's important
+ to point out that Bison is beginning to escape those limitations.
+ Moreover, these particular experimental features have very little
+ chance of being removed.
+ * src/getargs.c (usage): Say that IELR(1) and canonical LR(1) are
+ experimental.
