6cee62971e * data/lalr1.cc: Do not use @output_header_name@ unless
b4_defines_flag is set.

b2a836b51e * data/yacc.c (YYERROR): Move code from yyerrlab1 to here, so that
we don't need to worry about yyerrlab1 being reported as an
"unused label" by non-GCC C compilers.

* data/lalr1.cc (parse::yyerrlab1): When popping the stack, stop
when the stacks contain one element, as the loop would otherwise
free the last state, and then use the top state (the one we just
popped).  This means that the initial elements will not be freed
explicitly, as is the case in yacc.c; it is not a problem, as
these elements have fake values.

reduce/reduce conflicts.

33167b8b05 If the user does not define YYSTYPE as a macro, Bison now declares it
using typedef instead of defining it as a macro.  POSIX requires this.
For consistency, YYLTYPE is also declared instead of defined.

%union directives can now have a tag before the `{', e.g., the
directive `%union foo {...}' now generates the C code
`typedef union foo { ... } YYSTYPE;'; this is for Yacc compatibility.
The default union tag is `YYSTYPE', for compatibility with Solaris 9
Yacc.  For consistency, YYLTYPE's struct tag is now `YYLTYPE'
instead of `yyltype'.

`yystype' and `yyltype' are now obsolescent macros instead of being
typedefs or tags; they are no longer documented and will be
withdrawn in a future release.

996b1c7e8c * data/glr.c, data/lalr1.cc, data/yacc.c: Do not use __file__,
since this causes problems when __file__ contains character
sequences like "@" that are treated specially by src/scan-skel.l.
Instead, just use the file's basename.  This fixes the bug
reported by Martin Mokrejs in
<http://mail.gnu.org/pipermail/bug-bison/2002-December/001949.html>.

580043087e * lib/argmatch.c, lib/argmatch.h: Sync with gnulib.
Avoid use of <assert.h>, as the GNU Coding Standards hint that one
should use `if (! x) abort ();' rather than `assert (x);', and
anyway it's one less thing to worry about configuring.

76ae81983c * data/glr.c (yygetLRActions): Replace `yyindex' with
`yytable[yyindex]' to fix typo introduced in my 2002-11-09 patch.

<http://mail.gnu.org/pipermail/bug-bison/2002-November/001892.html>.

* data/yacc.c (yy_stack_print, YY_STACK_PRINT, yy_reduce_print)
(YY_REDUCE_PRINT): New.
(yyparse): Use them.
* data/glr.c (yy_reduce_print): Use YYFPRINTF, no need for
YYDPRINT here.
(yyglrReduce, yyrecoverParseError, yyparse): Don't report the
state reached after the reduction/recovery, since...
(yyparse, yyprocessOneStack): Report the state we are entering in.

c5e3e51055 * src/getargs.h, src/getargs.c (trace_e, trace_args, trace_types):
Add support for --trace=skeleton.
* src/scan-skel.l: %option debug.
Scan strings of non-@ or n instead of character by character.
(scan_skel): Handle trace_skeleton.
(QPUTS): New.
(@output_parser_name@, @output_header_name@): ``Restore'' their
support (used to be M4 macros).
* data/yacc.c: Quote larger chunks, a la glr.c.
* data/lalr1.cc: Likewise.
The header guards are no longer available, so use some other
string than `YYLSP_NEEDED'.

4c6cc1db75 Make the ``Printers and Destructors'' test more verbose, taking
`yacc.c''s behavior as (possibly wrong) reference.
* tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Use printf
instead of fprint on stdout.
Set and report the last_line of the symbols.
Consistently display values and locations.

src/conflicts.c, src/parse-gram.y, src/tables.c, src/tables.h,
tests/action.at, tests/calc.at, tests/conflicts.at,
tests/cxx-type.at, tests/regression.at:
"parse error" -> "syntax error" for POSIX compatibility.
"parsing stack overflow..." -> "parser stack overflow" so
that code matches Bison documentation.

0f39aab92a * src/parse-gram.y (declaration): Have %parse-param and %lex-param
take two BRACED_CODE, not two string_content.
Free the scanner's obstack when we are done.
(code_content): New.
* tests/calc.at: Adjust.

Paul Eggert
8fcc7db138 * tests/headers.at (AT_TEST_CPP_GUARD_H): Don't assume that
"$CC -E foo.h" is allowed, as this doesn't work with the Portland
Group compiler.  Instead, use "$CC -E bar.c".  Include the .h
file twice in the grammar, as an extra check.

* tests/input.at (Torturing the Scanner): Surround the
backslash-newline tests with "#if 0", to make it less likely that
we'll run into compiler bugs.  Bring back solitary \ inside
comment, but add a closing comment to work around HP C bug.  Don't
test backslash-newline in C character constant.  This should fix
the input.at bug reported by Nelson H. F. Beebe in
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001893.html>.
