Rename yystack everywhere to yystackp except in yyparse where it's not
a pointer.

consistency.

* data/c.m4 (b4_yydestruct_generate, b4_yysymprint_generate):
Prepend /*ARGSUSED*/, for lint's sake.

* data/glr.c (yyuserAction, yyuserMerge, yy_reduce_print):
(yyrecoverSyntaxError): Prepend /*ARGSUSED*/.
* data/glr.cc (YYLLOC_DEFAULT): Omit /*CONSTCOND*/ since this code
is C++ only.
* data/lalr1.cc (YYUSE): Just use a cast, since this code is C++ only.
* data/yacc.c (YYSTACK_FREE) [defined YYSTACK_ALLOC]:
Use YYID(0) rather than 0, for lint.
(yystrlen): Rewrite to avoid lint warning about ptrdiff_t overflow.
(yysyntax_error): Rewrite to avoid lint warnings about parenthesization.
stacks, and iterate another stack in order to call user
destructors.
* tests/glr-regression.at (No users destructors if stack 0 deleted):
New test case.
(Duplicated user destructor for lookahead): This test now is expected
to succeed.
it's no longer just a file.
* data/glr.c: Grant a special exception for C GLR parsers, that
reads like the already-existing exception for C LALR(1) parsers.
* data/glr.cc: Likewise.

* data/yacc.c: Reword the "written by" statement to clarify that
it was the parser skeleton, not the entire output file.

* data/glr.cc: Written by Akim Demaille.
* data/lalr1.cc: Likewise.
Fix typos in previous change that broke 'make check'.
YY_REDUCE_PRINT cannot be a pseudo-varargs macro; that isn't
supported in C.
* tests/calc.at (_AT_CHECK_CALC,_AT_CHECK_CALC_ERROR):
Don't check NUM-STDERR-LINES, since the output format is fluctuating.
We can revert this once things settle down.
when %expect fails because there were no conflicts.
* doc/bison.texinfo (Expect Decl): Tighten up wording in previous
change.
* tests/conflicts.at (%expect not enough, %expect too much):
(%expect with reduce conflicts): Adjust to new behavior.
* src/conflicts.c (conflicts_print): Unsatisfied %expectation are
errors.
* NEWS: Document this.
* doc/bison.texinfo (Expect Decl): Likewise.
* data/c.m4 (b4_parse_param_for, b4_parse_param_use): New.
* data/glr.c, data/glr.cc: Use them.
* data/glr.c (YYUSE): Have a C++ definition that supports
non-pointer types.
* data/glr.c (b4_shared_declarations): New.
Output them verbatim in the parser if !%defines, otherwise
output then in the header file, and include it instead.
* data/location.cc (position::initialize, location::initialize): New.
(position::position, location::location): Define only if
b4_location_constructors is defined.
* data/lalr1.cc (b4_location_constructors): Define it for backward
compatibility.

Reported by Alexandre Duret-Lutz.

final_state.
(save_reductions): Do it here.
(get_state): Alpha conversion.
(generate_states): Use a for loop.
* src/gram.h (item_number_is_rule_number)
(item_number_is_symbol_number): New.
* src/state.c: Use assert.
* src/system.h: Include assert.h.
* tests/sets.at (Accept): New.
(yyresolveAction): Initialize default location properly for empty right-hand
sides.
(yydoAction): Ditto. Add comment explaining apparently dead code.
* tests/glr-regression.at
(Incorrectly initialized location for empty right-hand side in GLR): New test.
header file names.
* tests/output.at (AT_CHECK_OUTPUT): Support subdirectorioes, and
additional checks.
Use this to exercise C++ outputs in subdirs.
Reported by Oleg Smolsky.
__STDC_VERSION__, as IBM cc 7.0 doesn't define the latter either.
Problem reported by John P. Hartmann.
* data/yacc.c (YYMODERN_C): Likewise. Don't define if the user has
already defined it.
as __STDC__, as IBM cc defines the former but not the latter.
* data/yacc.c (YYMODERN_C): New macro, which also looks at
__STDC_VERSION__. Use it everywhere instead of looking at
__STDC__ and __cplusplus.
