* src/reader.c (grammar_rule_check): When warning about the value of a
midrule action, use the location of the midrule action instead of the
location of the rule.
the location of the part of the rule.
* tests/actions.at (Default %printer and %destructor for mid-rule values):
Adjust expectations
* tests/input.at (Unused values with default %destructor): Ditto.
(AT_CHECK_UNUSED_VALUES): Ditto.
And use -fcaret.
* doc/figs/example.dot, doc/figs/example.y: New.
* doc/bison.texi: Prefer "token" to TOKEN.
Use @group where appropriate.
Adjust with style changes in the output (State 0, not state 0).
Fix some @ref that were missing the third argument.
Fix some incorrect line numbers.
Use "nonterminal", not "non-terminal".
Fix overfull and underfull TeX hboxes.
Put the comments in the index.
Remove duplicate index entries.
Fuse glossary entries where appropriate.
(Understanding): Improve the continuity between sections.
Use example.dot to show the whole graph.
* doc/Makefile.am: Adjust.
* m4/c-working.m4 (BISON_LANG_COMPILER_POSIXLY_CORRECT): New.
(BISON_C_COMPILER_POSIXLY_CORRECT): Use it.
For consistency with C++, also define BISON_C_WORKS.
* m4/cxx.m4 (BISON_CXX_COMPILER_POSIXLY_CORRECT): New.
* configure.ac: Use it.
* tests/atlocal.in: Get its result.
Propagate properly CXX values when used to compile C.
When POSIXLY_CORRECT, adjust BISON_C_WORKS and BISON_CXX_WORKS.
* tests/local.at (AT_COMPILE): Use BISON_C_WORKS.
* cfg.mk: Exclude names-refs, it includes a "double" if (end of first
line, first of second line below).
test.y:43.12-44.59: symbol not found in production: if
if-stmt-a: IF expr[cond] THEN stmt.list[then] ELSE stmt.list[else] FI
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Fixes a -Werror failure of xalloc.h used in src.

* configure.ac: Check whether GCC pragma diagnostic push/pop works.
Enable these warnings for bison if it does.
Enable these warnings for the test suite anyway.
* origin/maint:
misc: pacify the Tiny C Compiler
cpp: make the check of Flex version portable
misc: require getline
c++: support wide strings for file names
doc: document carets
tests: enhance existing tests with carets
errors: show carets
getargs: add support for --flags/-f

Work on some other areas of Bison revealed that some macros expanded
to be expanded only once were actually expanded several times. This
was due to the fact that changecom was not properly restored each
time, and macro names appearing in comments were then expanded.
Introduce begin/end macros which are easier to match that
changecom()/changecom(#).

* data/glr.c, data/glr.cc, data/lalr1.cc, data/lalr1.java,

Use them.
