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/lalr1.cc: Likewise.
* data/location.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.c: Written by Paul Hilfinger.
* 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.

__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.
(xlc and xlC_r) reported by John P. Hartmann.
* data/location.cc (initial_column, initial_line): Remove.
All uses replaced by 0 and 1.
* src/scan-gram.l (gram_wrap): Redefine to avoid bug in flex 2.5.31
that xlc complains about.
* src/scan-skel.l (skel_wrap): Likewise.
Use YYUSE instead of casting to void.
* data/glr.c (YYUSE): New macro.
(yyuserMerge, yyreportAmbiguity, yyreportSyntaxError):
Use it instead of rolling our own.
(YYLLOC_DEFAULT, YYCHK, YYDPRINTF, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
(YYCHK1):
Use /*CONSTCOND*/ to suppress lint warnings.
* data/lalr1.cc (YYLLOC_DEFAULT, YY_SYMBOL_PRINT, YY_REDUCE_PRINT):
(YY_STACK_PRINT): Use 'false' not '0'.
(YYUSE): New macro.
(yysymprint_, yydestruct_): Use it instead of rolling our own.
* data/yacc.c (YYUSE): New macro.
(YYCOPY, YYSTACK_RELOCATE, YYBACKUP, YYLLOC_DEFAULT):
(YYDPRINTF, YY_SYMBOL_PRINT, YY_STACK_PRINT, YY_REDUCE_PRINT):
(yyerrorlab): Use /*CONSTCOND*/ to suppress lint warnings.
Use assignments rather than casts-to-void to suppress
unused-variable warnings. This pacifies 'lint'.
* data/lalr1.cc (yysymprint_, yydestruct_): Use a call to suppress
unused-variable warnings.
GNU/Linux and Solaris that support unlocked I/O. The basic idea
is to use the gnlib unlocked-io module, and to prefer putc and
puts to printf when either will work (since the latter doesn't
come in an unlocked flavor).
* bootstrap (gnulib_modules): Add unlocked-io.
* data/c.m4 (yysymprint): Prefer puts and putc to printf.
* data/glr.c (YYFPUTC, YYFPUTS, YYDPUTS): New macros.
Prefer them to YYFPRINTF and YYDPRINTF if either will do,
and similarly for puts and putc and printf.
* data/yacc.c: Likewise.
* lib/bitset.c (bitset_print): Likewise.
* lib/bitset.h [USE_UNLOCKED_IO]: Include unlocked-io.h.

* src/getargs.c: Use ARGMATCH_VERIFY rather than verify.
* src/system.h (verify): Remove.
Include verify.h instead.
* src/tables.c (tables_generate): Use new API for 'verify'.
* bootstrap (gnulib_modules): Remove alloca. Bison doesn't need
it itself.
* src/main.c (main) [C_ALLOCA]: Don't flush alloca'ed memory; we
don't use alloca any more.
* data/yacc.c [YYSTACK_USE_ALLOCA && !defined __GNUC__ && ! defined
__BUILTIN_VA_ARG_INCR && ! defined _AIX && ! defined _MSC_VER &&

to match yacc.c, to test more hosts.
doesn't affect behavior.
(YYSTACK_ALLOC) [YYSTACK_USE_ALLOCA]: Improve support for
Solaris, AIX, MSC.
(_STDLIB_H): Renamed from YYINCLUDED_STDLIB_H. All uses changed.
This works a bit better with glibc, if user code has already included
stdlib.h.
* doc/bison.texinfo (Bison Parser): Document that users can't
arbitrarily use malloc and free for other purposes. Document
that <alloca.h> and <malloc.h> might be included.
(Table of Symbols): Under YYSTACK_USE_ALLOCA, Don't claim that the
user must declare alloca.
(YYSTACK_ALLOC_MAXIMUM): Use it.
(yysyntax_error): New function.
(yyparse) [YYERROR_VERBOSE]: Don't leak memory indefinitely if
multiple syntax errors are reported, and alloca is being used.
Instead, reallocate buffers twice as big each time, so that
we waste at most half the allocated memory. Start with a small
(128-byte) buffer that will suffice in most cases anyway.
Use yysyntax_error to do most of the work.
Mark it as expected to fail.
Cast result of malloc; problem reported by [email protected].
* tests/actions.at, tests/calc.at, tests/glr-regression.at:
Don't start user-code symbols with "yy", to avoid name space problems.

official release.

diagnostic.
* src/output.c (prepare): Likewise.
* data/lalr1.cc (YYERROR_VERBOSE_IF): New macro.
(yysyntax_error_): Use it to avoid GCC warning when YYERROR_VERBOSE
is not defined. This is an awful hack, but it's enough for now.
All callers changed.
* tests/glr-regression-at (make_value): Args are const pointers now,
to avoid GCC warning.
(Duplicated user destructor for lookahead): New test. Currently
skipped. It fails on my host but I'm not sure it'll always fail.
* doc/bison.texinfo (Parser Function): Document when yyparse
returns 2.
* data/lalr1.cc: Revert part of previous change, as it's incompatible.
(b4_filename_type): Renamed back from b4_file_name_type. All uses
changed.
(class position): file_name -> filename (reverting). All uses changed.
(YYJMP_BUF, YYSETJMP, YYLONGJMP) [!defined YYSETJMP]: New macros.
All uses of jmp_buf, setjmp, longjmp changed to use these instead.
(yyparse): Abort if user code uses longjmp to throw an unexpected
value.
"file" or "name", depending on the context.
(Invocation): The output of "bison hack/foo.y" goes to foo.tab.c,
not to hack/foo.tab.c.
(Calc++ Top Level): 2nd arg of main is not const.
All uses changed. Invoke user destructor after an error during a
split parse (trivial change from Joel E. Denny).
* tests/glr-regression.at
(User destructor after an error during a split parse): New test case.
Problem reported by Joel E. Denny in:
http://lists.gnu.org/archive/html/bison-patches/2005-08/msg00029.html
in yydestruct diagnostic, since it might not be an error.

with the other templates, and to fix bogus run-on messages such
as the one reported at the end of
<http://lists.gnu.org/archive/html/help-bison/2005-07/msg00040.html>.
All callers changed to avoid the newline.
(yyprocessOneStack): Output two lines rather than one, to accommodate
the above change. This changes the debug output format slightly.
AT_PARSER_CHECK for data that contains backslashes. It currently
uses 'echo', and 'echo' isn't portable if its argument contains
backslashes. Problem found on OpenBSD 3.4. Also, do not assume
that the byte '\0xff' is not printable in the C locale; it is,
under OpenBSD 3.4 (!). Luckily, '\0x80' through '\0x9e' are
not printable, so use '\0x81' to test.
* data/glr.c (ATTRIBUTE_UNUSED): Remove, since it infringes on
the user's name space. All uses changed to __attribute__
((__unused__)).
(yyFail, yyMemoryExhausted, yyreportAmbiguity):
Add __attribute__ ((__noreturn__)).
* etc/clcommit: Remove. We weren't using it, and it failed
"make maintainer-distcheck".
* Makefile.maint: Merge from coreutils.

(makefile_path_separator_check, copyright-check):
Use grep -n, to make it easier to find violations.
Use CVS_LIST and CVS_LIST_EXCEPT.
(header_regexp, h_re): Remove.
(dd_c): New macro.
(sc_dd_max_sym_length, .re-list, news-date-check): New rules.
(my-distcheck): Use more-modern GCC flags.
(signatures, %.asc): Remove.
(rel-files, announcement): Remove signatures.
Restore old updating code, even though we don't use it, so
that we're the same as coreutils.
