9114b267a8 c++: beware of to_string portability issues 
Reported by Bruno Haible.
http://lists.gnu.org/archive/html/bug-bison/2019-05/msg00033.html

* m4/bison-cxx-std.m4 (_BISON_CXXSTD_11_snippet): Check it.

f5a4e279bc build: use gettext-h 
We were using the gnulib's gettext module with tricks in
bootstrap.conf to avoid useless files.  Instead, use gnulib's
gettext-h module.

* .travis.yml: Force Gettext 0.18.3 on Trusty.
* bootstrap.conf: Use gettext-h instead of gettext.
(excluded_files): Remove.
* configure.ac (AM_GNU_GETTEXT_VERSION): Bump to 0.19.

4d34b06fb3 diagnostics: use gnulib's libtextstyle-optional 
Bruno Haible just added a default implementation of libtextstyle's
interface when the library is not available.
https://lists.gnu.org/archive/html/bison-patches/2019-03/msg00025.html

* gnulib: Update.
* bootstrap.conf: Replace libtextstyle with libtextstyle-optional.
* src/complain.c, src/getargs.c: Remove now useless cpp guards.

01855ca328 warnings: don't use _Noreturn with G++ 4.7 in C++98 mode 
The timevar and bitset modules now use the c99 module which causes
$CXX to now include -std=gnu++11 when possible.  Unfortunately, G++
4.7 does not implement [[noreturn]] in C++11 mode, so our tests of
glr.cc (which uses _Noreturn) fail with

    input.cc:954:1: error: expected unqualified-id before '[' token

right before [[noreturn]].  4.8 works fine.

* data/skeletons/c.m4 (b4_attribute_define): Do not use [[noreturn]]
with GCC 4.7.

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.

https://lists.gnu.org/archive/html/bison-patches/2019-03/msg00007.html

* bootstrap.conf (gnulib_modules): Use libtextstyle when possible.
* data/diagnostics.css: New.
* src/complain.c (begin_use_class, end_use_class, flush)
(severity_style, complain_init_color): New.
Use them.
* src/getargs.c (getargs_colors): New.
(getargs): Use it.
Skip --color and --style.
* src/location.h, src/location.c (location_print): Use a style.

* tests/bison.in: Force --color=yes when stderr is a tty.
* tests/local.at: Disable colors during the test suite.
* tests/input.at: Adjust expectations to the extra options passed on
the command line.

a4ede8f85b package: make bison a relocatable package 
Suggested by David Barto
https://lists.gnu.org/archive/html/help-bison/2015-02/msg00004.html
and Victor Zverovich.
https://lists.gnu.org/archive/html/bison-patches/2018-10/msg00121.html

This is very easy to do, thanks to work by Bruno Haible in gnulib.
See "Supporting Relocation" in gnulib's documentation.

* bootstrap.conf: We need relocatable-prog and relocatable-script (for yacc).

* src/yacc.in: New.
* configure.ac, src/local.mk: Instantiate it.
* src/main.c, src/output.c (main, pkgdatadir): Use relocatable2.

* doc/bison.texi (FAQ): Document it.

cf1446dc9e tests: don't fail if the C++ compiler does not work 
Also, make sure that `make dist` generates a correct tarball even if
the C++ compiler does not work.

Reported by Nelson H. F. Beebe.

* m4/cxx.m4 (BISON_CXX_WORKS): Define to true/false instead of
true/exit 77.  The latter is too dangerous to use (it directly quits).
(ENABLE_CXX): New name for the Automake conditional, for consistency
with ENABLE_CXX11 etc.
* tests/local.at (AT_COMPILE, AT_COMPILE_CXX): Adjust to the new
semantics of BISON_CXX_WORKS.
* examples/c++/local.mk: Skip the variant test if C++ does not work.
* examples/calc++/local.mk: Likewise.

5649888686 build: use our own version of ax_check_link_flag 
The message on configure is misleading:

    checking whether the linker accepts -std=c++11... yes
    checking whether the linker accepts -std=c++14... yes
    checking whether the linker accepts -std=c++17... no

It is the compiler that we check, not just the linker.

* m4/ax_check_link_flag.m4: Remove.
* m4/bison-check-compiler-flag.m4: New.
* m4/bison-cxx-std.m4: Use it.

e40a3eed34 build: fix Autoconf macros to check for C++ standard flags 
* m4/bison-cxx-std.m4: Since now we link the program, we need a

49dc1b5bf1 build: don't accept a broken standard lib for C++ 
On the CI, we had failures such as:

    ./c++.at:401:  $PREPARSER ./list
    stderr:
    ./list: error while loading shared libraries: libc++.so.1:
            cannot open shared object file: No such file or directory

because we accepted `-std=c++ -stdlib=libc++` although libc++ is not
installed on the machine.

* m4/ax_check_compile_flag.m4 (AX_CHECK_COMPILE_FLAG): Rewrite as...
* m4/bison-check-compile-flag.m4 (BISON_CHECK_COMPILE_FLAG): this, so
that we use AC_LINK_IFELSE to check the compiler (and its std lib)
instead of AC_COMPILE_IFELSE.

3367d8dd5c build: strengthen the C++ standard flag test 
On the CI, we have this spurious failure with clang 3.9 with
-std=c++17:

    In file included from list.y:23:
    In file included from /usr/include/c++/4.8/iostream:39:
    In file included from /usr/include/c++/4.8/ostream:38:

    /usr/include/c++/4.8/cstdio:120:11: error: no member named 'gets' in the global namespace
      using ::gets;
            ~~^

This shows that our test, based on gl_WARN_ADD, is a joke.  We have to
really check for at least a bit of C++.

* m4/ax_check_compile_flag.m4, m4/bison-cxx-std.m4: New.
* configure.ac: Use them to make sure the compiler actually works.
