dee8fbbc1e gram: fix and improve log message 
It seems that not many people read these logs: the error was
introduced in 2001 (3067fbef53),

* src/gram.c (grammar_dump): Fix the headers of the table: remove
duplicate display of "Ritem Range".
While at it, remove duplicate display of the rule number (and remove
an incorrect comment about it: these numbers _are_ equal).
* tests/sets.at (Reduced Grammar): Use useless rule, nterm and token
in the example.

f6e38d7ac9 diagnostics: use libtextstyle for colored output 
Bruno Haible released libtextstyle, a library for colored output based
on CSS.  Let's use it to generate colored diagnostics, provided
libtextstyle is available.

7c64b1f4ff tests: fight G++ warnings about zero as null pointer constant 
In C++ pre C++11 it is standard practice to use 0 for the null pointer.
But GCC pre 8 -std=c++98 with -Wzero-as-null-pointer-constant warns about
this.

So disable -Wzero-as-null-pointer-constant when compiling C++ pre 11.
Let's do this in AT_DATA_SOURCE_PROLOGUE (which is pasted on top of
all the test grammar files).  Unfortunately, that shifts all the
locations in the expected error messages, which would be too noisy.
Instead, let's introduce testsuite.h, which can vary in length, and
include it in AT_DATA_SOURCE_PROLOGUE.

* tests/testsuite.h: New.
Disable -Wzero-as-null-pointer-constant's warning with GCC pre 8,
C++ pre 11.
* tests/local.at (AT_DATA_SOURCE_PROLOGUE): Use it.
* tests/atlocal.in (CPPFLAGS): Find it.
* tests/local.mk: Ship it.

026816664f tests: skip C++ tests that are too demanding for some compilers 
Some tests now fail when compiled with G++ 4.3 or 4.4 on MacPorts.

* tests/local.at (AT_SKIP_IF_EXCEPTION_SUPPORT_IS_POOR): New.
* tests/c++.at (Exception safety): Use it.

e4678430c2 diagnostics: "-Werror -Wno-error=foo" must not emit errors 
Currently "-Werror -Wno-error=foo" still turns "foo" warnings into errors.
Reported by Alexandre Duret-Lutz.
See http://lists.gnu.org/archive/html/bug-bison/2013-09/msg00015.html.

* src/complain.c (errority, errority_flag): New.
(complain_init): Initialize the latter.
(warning_argmatch): Extract the loop iterating on the flag's bits.
Set and unset errority_flag here.
(warnings_argmatch): -Wno-error is not the same as -Wno-error=everything:
we must remember if category foo was explicitly turned in an error/warning
via -W(no-)error=foo.
(warning_severity): Use errority_flag.

* tests/input.at (Symbols): Just check --yacc, not -Wyacc, that's the
job of tests on -W.
(-Werror is not affected by -Wnone and -Wall): Rename as...
(-Werror combinations): this.
Tests more combinations of -W, -W(no-)error, and -W(no-)error=foo.
* tests/local.at (AT_BISON_CHECK_WARNINGS): Don't expect -Werror
to turn runs that issue warnings into runs with errors, as the
warnings might be enforced as warnings by -Wno-error=foo, in which
case -Werror does not change anything.

* doc/bison.texi (Bison Options): Try to be clearer about how
-W(no-)error and -W(no-)error=foo interact.

b7171c45f4 tests: skip C++ tests if we can't compile a simple program 
There are possible conflicts between gnulib replacement functions (in
<stdio.h>) and their C++ wrappers (in <stream>).  Trying to address
these in configure seems too hard, and I don't know how to fix the issue
in gnulib.  Cowardly avoid the problem by skipping C++ tests when this
happens.
Reported by Stefano Lattarini.
http://lists.gnu.org/archive/html/bug-bison/2013-06/msg00001.html

* tests/atlocal.in (BISON_CXX_WORKS): Also set it to "skip" if we can't
compile a simple program using <stream>.
* tests/local.at: Comment changes.

6ce4b4ff1b muscle: check more cases of %define variables with code values 
* data/bison.m4 (b4_percent_define_check_kind): Fix overquotation.
(api.location.type, api.position.type): Check they have code values here.
* data/c++.m4 (api.location.type): No longer checked here.
(parser_class_name): Check it here.
* data/java.m4 (api.value.type, init_throws, lex_throws, parser_class_name)
(throws, annotations, extends, implements): Check they have code values.
* doc/bison.texi: Fix every incorrect occurrence of %define.
Document the additional syntax for %define: code values.
Document the additional syntax for -D/-F: string and code values.
* tests/calc.at, tests/headers.at, tests/input.at, tests/java.at,
* tests/local.at: Fix dependencies.

630a021850 api.token.prefix: use code values 
* data/bison.m4: Remove useless (and incorrect: m4_* instead of b4_*)
default assignment to api.token.prefix.
Check that api.token.prefix is assigned code.
* tests/input.at (%define code variables): New test.
* NEWS, doc/bison.texi, tests/c++.at, tests/calc.at,
* tests/java.at, tests/local.at: Adjust to use braces.
