6373b90fc8 Port better to C++ platforms 
* data/skeletons/yacc.c (YYPTRDIFF_T, YYPTRDIFF_MAXIMUM):
Default to long, not int.
(yy_lac_stack_realloc, yy_lac, yytnamerr, yyparse):
Avoid casts to YYPTRDIFF_T that were masking the problem.

2713e7c4ff TODO: update 
I no longer agree with that item, there are indeed two things to
report: lack of definition, and being useless.  We could have either
one without the other, they are not directly related.

57290d63fd package: various fixes for syntax-check 
* cfg.mk: Disable checks where needed (e.g., we do want to check the
behavior with tabs).
(sc_at_parser_check): Remove.  Unfortunately since
a11c144609 we no longer use the './'
prefix to run programs in the current directory.  That was so that we
could run Java programs like the other, although they are no run with
the `./` prefix (see 967a59d2c0).
As a consequence this sc check no longer makes sense.
However, since now AT_PARSER_CHECK passes the `./` prefix itself, this
sc-check was superfluous.
* examples/c/reccalc/scan.l: Use memcpy, not strncpy.
* src/ielr.c, src/reader.c: Obfuscate "lr(0)" so that the sc-check for
"space before paren" does not fire.
* tests/diagnostics.at: Avoid space-tab, use tab-tab.

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.

20b0746793 parser: improve the error message for symbol class redefinition 
Currently our error messages include both "symbol redeclared" and
"symbol redefined", and they mean something different.  This is
obscure, let's make this clearer.

I think the idea between 'definition' vs. 'declaration' is that in the
case of the nonterminals, the actual definition is its set of rules,
so %nterm would be about declaration.  The case of %token is less
clear.

* src/symtab.c (complain_class_redefined): New.
(symbol_class_set): Use it.
Simplify the logic of this function to clearly skip its body when the
preconditions are not met.
* tests/input.at (Symbol class redefinition): New.

7a45fc35bf yacc.c: fix warnings about integral types 
Reported by Derek Clegg.
http://lists.gnu.org/archive/html/bug-bison/2018-10/msg00018.html

Rather than adding casts, we should be more careful with types.  For
instance yystate should be a yytype_int16.  But currently we can't: it
is also used sometimes for storing other things that state numbers.

* data/yacc.c (yyparse): Add missing casts.

1048a1c901 errors: change output, and improve -y coherence 
The prefix of warnings treated as errors is now "error: ". Also, their
suffix now reflects the changes in the Werror option format.

An output for -Werror=other used to be:
  bison: warnings being treated as errors
  input.y:1.1: warning: stray ',' treated as white space [-Wother]

It is now:
  bison: warnings being treated as errors
  input.y:1.1: error: stray ',' treated as white space [-Werror=other]

The line "warnings being treated as errors" no longer adds any info,
it will be removed in a forthcoming change.

* NEWS: Add entry "Enhancement of the -Werror"
* doc/bison.texi: Move the warnings-as-error to a new bullet.
* src/complain.c (complains): Refactor, change the prefix of warnings
that are treated as errors.
(warnings_print_categories): Support for [-Werror=CATEGORY] display
* src/getargc.c (getargs): -y implies -Werror=yacc
