The syncline tests, which try to recognize compiler diagnostics,
are confused by escapes for colors.
* configure.ac (warn_tests): New, to factor the warnings for both
C and C++ tests.
Add -fno-color-diagnostics to it.
* tests/local.at (AT_TEST_TABLES_AND_PARSE): Do not remove glue
together compiler flags.
Conflicts:
configure.ac
When fed with foo.c, clang++ 3.2 answers:
clang: error: treating 'c' input as 'c++' when in C++ mode,
this behavior is deprecated
* tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Use *.cc and *.hh
for C++.
Reported by Rob Conde.

* data/c.m4 (b4_symbol_actions): Rename as...
(_b4_symbol_actions): this.
(b4_symbol_actions): New wrapper.
Do not emit empty switches.
Adjust all b4_symbol_actions callers.
Reported by Rob Conde.
http://lists.gnu.org/archive/html/bug-bison/2013-03/msg00003.html
* data/stack.hh (operator=, stack(const stack&)): Make this class
uncopyable, i.e., "undefine" these operators: make them private and
don't implement them.
(clear): New.
* data/lalr1.cc: Use it instead of an assignment.
(parser): Make this class uncopyable.
* data/glr.c, src/graphviz.h, src/ielr.c, src/scan-gram.l,
* src/system.h, tests/actions.at, tests/glr-regression.at: Do not
use // comments.
Do not introduce variables after statements.
Provide "main" with a return value.
* doc/bison.texi (Actions in Mid-Rule): Mention and use named references.
Split into three subsections, among which...
(Mid-Rule Action Translation): this new section.
On
%%
exp: {;} {$$;} { $$ = $1; }
instead of reporting (with -fcaret -Wmidrule-value)
midrule.y:2.6-8: warning: unset value: $$ [-Wmidrule-values]
exp: {;} {$$;} { $$ = $1; }
^^^
midrule.y:2.6-27: warning: unused value: $2 [-Wmidrule-values]
exp: {;} {$$;} { $$ = $1; }
^^^^^^^^^^^^^^^^^^^^^^

midrule.y:2.6-8: warning: unset value: $$

midrule.y:2.10-14: warning: unused value: $2

* 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.
* tests/actions.at: Unset value.
* tests/conflicts.at: Rule useless due to conflicts.
* tests/input.at: Missing terminator, unexpected end of file, command line
redefinition of variable.
* tests/named-refs.at: Many errors.
* tests/reduce.at: Useless nonterminals and rules.
* tests/regression.at: Large token.
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/bison.m4 (b4_output_begin, b4_output_end): New.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/lalr1.java,
* data/location.cc, data/stack.hh, data/yacc.c:
Use them.
