2b5a27ba3d Avoid compiler warnings 
At least GCC 7.3, with -O1 or -O2 (but not -O0 or -O3) generates
warnings with -Wnull-dereference when using yyformat: it fails to see
yyformat cannot be null.

Reported by Frank Heckenbach, https://savannah.gnu.org/patch/?9620.

* configure.ac: Use -Wnull-dereference if supported.
* data/glr.c, data/lalr1.cc, data/yacc.c: Define yyformat in such
a way that GCC cannot not see that yyformat is defined.
Using `default: abort();` also addresses the issue, but forces
the inclusion of `stdlib.h`, which we avoid.

8d4dc896cb yacc.c: fix broken union when api.value.type=union and %defines are used 
Reported by Rich Wilson.

* data/c.m4 (b4_symbol_type_register): Append to b4_union_members,
not b4_user_union_members.
The latter invokes the former, but it is the former which is reinitialized
to empty by b4_value_type_setup_union.
* tests/types.at: Check it.

This reveals another bug, this time in the case of glr.c parsers.

* data/glr.c: Generate the header file before the implementation file,
to be sure that the setup is run before what depends on it.

f0f95a50ee c: no longer require stdio.h when locations are enabled 
Recent changes (in 2.7) introduced a dependency on both FILE and
fprintf, which are "available" only in %debug mode.  This was to
define yy_location_print_, which is used only in %debug mode by the
parser, but massively used by the test suite to output the locations
in yyerror.

Break this dependency: the test suite should define its own routines
to display the locations.  Eventually Bison will provide the user with
a means to display locations, but not yet.

* data/c.m4 (b4_yy_location_print_define): Use YYFPRINTF instead of
fprintf directly.
* data/yacc.c (b4_yy_location_print_define): Invoke it only in %debug
mode, so that stdio.h is included (needed for FILE*), and YYFPRINTF
is defined.

* tests/local.at (AT_YYERROR_DECLARE, AT_YYERROR_DEFINE): Declare
and define location_print and LOCATION_PRINT.

* tests/actions.at, tests/existing.at, tests/glr-regression.at,
* tests/input.at, tests/named-refs.at, tests/regression.at: Adjust
to use them.
Fix the expected line numbers (as the prologue's length has changed).

1c7ec959b1 m4: use a safer pattern to enable/disable output 
Work on some other areas of Bison revealed that some macros expanded
to be expanded only once were actually expanded several times.  This

a1d1ab50a0 glr.cc, yacc.c: initialize yylloc properly 
There are several issues to address here.  One is that yylloc should
be initialized when possible.  Another is that the push parser needs
to update yypushed_loc when the user modified it.  And if the parser
starts by a reduction of an empty, it uses the first location on the
stack, which, therefore, must also be initialized to this initial
location.

This is getting complex, especially since because initializing a
global (impure interface) is different from initializing a local
variable.  To simplify, the local yylloc is not initialized during its
definition.

* data/c.m4 (b4_yyloc_default_define): Replace by...
(b4_yyloc_default): this.
Adjust dependencies.
* data/glr.cc: Initialize yylloc.
* data/yacc.c (b4_declare_scanner_communication_variables):

Don't define yyloc_default.
(yypush_parse): The location formal is not const, as we might
initialize it.
(yyparse): Define yyloc_default.
Use it before running the user initial action.
Possibly update the first location on the stack, and the pushed
location after the user initial action.
* tests/actions.at (Initial locations): Check that the initial
location is correct.

a68b1f237e yacc.c: initialize yylval and yylloc. 
When generating a pure push parser, the initialization of yylval and
yylloc may not be visible to the compiler.  With warnings enabled, GCC
4.3.6, 4.4.7, 4.5.4, and 4.6.3 report uninitialized uses of
yylval/yylloc.  Using local pragmas to disable these warnings is not
supported before 4.6, and 4.6 does not support it properly.  So
initialize yylval and yylloc at their definition.  Reported by Peter
Simons.  See
http://lists.gnu.org/archive/html/bison-patches/2012-10/msg00133.html

* data/c.m4 (b4_yyloc_default_define): New.
* data/yacc.c: Use it when locations are requested.
(YYLVAL_INITIALIZE): Replace by...
(YY_INITIAL_VALUE): this.
(yyparse): Initialize yylloc and yylval.
Therefore, remove the initialization of yylloc's field.
* data/glr.c: Likewise.

                        [-Werror,-Wparentheses-equality]

This is Apple clang version 3.1 (tags/Apple/clang-318.0.61).

* data/c.m4 (b4_table_value_equals): Use (!!(A == B)) instead of (A == B)
to avoid this warning.
Any reasonable compiler should generate the same code.
* src/uniqstr.h (UNIQSTR_EQ): Likewise.
* data/glr.c (LONGJMP): abort after longjmp to pacify clang.

e4c0985b5c glr.cc: %defines is no longer mandatory 
* data/glr.cc: No longer require %defines.
When it is not given, define the position and location classes instead
of including their headers.
(b4_shared_declarations): Use the original parse-params.
* data/glr.c (b4_shared_declarations): Define only if undefined.
* tests/actions.at, tests/calc.at: No longer force the use of %defines
for glr.cc.
* NEWS: Doc it.

56f8d56088 remove support for lint 
Basically revert commit 12ce2df60d.
http://lists.gnu.org/archive/html/bison-patches/2012-08/msg00004.html

* data/c.m4, data/glr.c, data/yacc.c (YYID): Remove.
No longer use ARGSUSED.
* src/getargs.c: Restore simpler inclusion of getopt.h (anyway, since
then we now use gnulib which certainly protects us from such issues).

dcd5344dcd yacc: remove trailing end of line at end of file 
There are still spurious spaces at the end of some lines.  But this is
addressed in the master branch, and I am reluctant to try to backport
this.

* data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: here.
* tests/calc.at (AT_CHECK_SPACES): New.
Use it.
Be sure not to introduce trailing empty lines in the *.y files.
* NEWS: Doc it.
* cfg.mk (syntax-check): Remove the exception.
