d7527048a8 maint: port to strict C function type checking 
Violation of C standard detected by clang -fsanitize=undefined
with clang 19.1.7 on Fedora 41 x86-64.

(hash_pair_free, hash_pair_table_create):
Avoid undefined behavior in C, which does not allow you to cast a
function pointer to some other function type and then call it via
that other type.  Instead, use functions with correct types
according to the C standard, and cast their parameters.
* src/getargs.c (xargmatch_fn): Return int const, not int, to
match what ARGMATCH_DEFINE_GROUP does.  In all uses of
ARGMATCH_DEFINE_GROUP, say that they return int, to match
xargmatch_fn.
(FLAGS_ARGMATCH): Do not cast function pointer.
* src/parse-simulation.c (vc_derivation_list_append): New function.
* src/system.h (deconst): New static function.

6571c2d1b1 warnings: don't complain about m4_foo and b4_foo when from the user 
Currently, occurrences of these identifiers in the user's input yield
spurious warnings.

To tell the difference between a legitimate m4_foo from the user, and
a bad m4_foo coming from a non-evaluated macro of a skeleton, escape
the user's identifiers as m4@'_foo.  We already use @' as a special
sequence to be stripped from the skeleton's output.

See <https://lists.gnu.org/r/bug-bison/2021-10/msg00026.html> and
previous commit ("warnings: be less picky about occurrences of m4_/b4_
in the output").

* src/flex-scanner.h (OBSTACK_SGROW): New.
* src/output.c (output_escaped): Escape m4_ and b4_.
* src/scan-code.l: Likewise.
* src/system.h (obstack_escape): Likewise.
And rewrite as a function.
* tests/skeletons.at (Suspicious sequences): Make sure the user can
use m4_foo/b4_foo without spurious warnings.

977e19840d portability: beware of max () with MSVC 
Reported by Maarten De Braekeleer.
https://lists.gnu.org/r/bison-patches/2020-07/msg00080.html

We don't want to use gnulib's min and max macros, since we use
function calls in min/max arguments.

* src/location.c (max_int, min_int): Move to...
* src/system.h: here.
* src/counterexample.c, src/derivation.c: Use max_int instead of max.

efbcadeca7 reports: don't escape the labels 
Currently we use "quotearg" to escape the strings output in Dot.  As a
result, if the user's locale is C for instance, all the non-ASCII are
escaped.  Unfortunately graphviz does not interpret this style of
escaping.

For instance:

    5 -> 2 [style=solid label="\"\303\221\303\271\341\271\203\303\251\342\204\235\303\264\""]

was displayed as a sequence of numbers.  We now output:

    5 -> 2 [style=solid label="\"Ñùṃéℝô\""]

independently of the user's locale.

* src/system.h (obstack_backslash): New.
* src/graphviz.h, src/graphviz.c (escape): Remove, use
obstack_backslash instead.
* src/print-graph.c: Likewise.
* tests/report.at: Adjust.

to https://lists.gnu.org/archive/html/bug-bison/2019-10/msg00073.html.

Paul Eggert's changes in gnulib do fix the issue for modern GCCs (7,
8, 9) on macOS.  Unfortunately these warnings are back on the
CI (GNU/Linux) with GCC 4.6, 4.7, (not 4.8) and 4.9.

Disable the warning locally.

* configure.ac (warn_common, warn_tests): Remove -Wtype-limits.
* src/system.h (IGNORE_TYPE_LIMITS_BEGIN, IGNORE_TYPE_LIMITS_END): New.
* src/InadequacyList.c, src/parse-gram.c, src/parse-gram.y,

ef51bfa744 c++: use nullptr for C++11. 
C++11 introduces "nullptr" which plays the role of C's NULL, in
replacement of "0".  Fix the C++ skeletons to avoid warnings about
uses of "0" in place of "nullptr", and improve C skeletons to also use
this "nullptr" when compiled with a C++11 compiler.

* configure.ac: More C++ warnings.
* NEWS (2.5.1): Document this.
* data/c++.m4, data/c.m4 (b4_null_define): New.
(b4_null): Use YY_NULL instead of 0.
* data/glr.c, data/lalr1.cc, data/location.cc, data/yacc.c:
Call b4_null_define/b4_null where appropriate.
Use YY_NULL instead of NULL.
* data/location.cc (initialize): Accept a default argument,
YY_NULL.
* tests/actions.at, tests/calc.at: Adjust.

* data/glr.c, lib/libiberty.h, src/system.h (__attribute__):
Do not disable it when __STRICT_ANSI__ is defined, as, for
instance, it disables the __attribute__((unused)) which
protects us from some compiler warnings.
This was already done elsewhere in Bison, in 2001, see
4a0d893695.
* tests/regression.at: Adjust output.

4663cb4d0c avoid direct strncmp calls. 
Before this change, bison would accept either .tab and _tab equivalently,
whatever the current platform.  Besides, it was not obeying everywhere
to the possible definition of TAB_EXT to something else than .tab.

For consistency, handle only TAB_EXT (".tab" on non DJGPP platforms).
Support for "_tab" is neither documented, nor tested.

	* src/system.h (STRNCMP_LIT): New.
	From Jim Meyering.
	(STRPREFIX_LIT): New.
	* src/files.c, src/getargs.c: Use it.
