directive. This directive's first argument is "complain", "warn", etc.

m4: the original one, and another, which is used for instance for
printers and destructors, variants etc. Move to using only the latter.

This change was made by applying emacs' untabify function to
nearly all files in Bison's repository. Required tabs in make
files, ChangeLog, regexps, and test code were manually skipped.
Other notable exceptions and changes are listed below.
* bootstrap: Skip because we sync this with gnulib.
* data/m4sugar/foreach.m4
* data/m4sugar/m4sugar.m4: Skip because we sync these with
Autoconf.
* djgpp: Skip because I don't know how to test djgpp properly, and
this code appears to be unmaintained anyway.
* README-hacking (Hacking): Specify that tabs should be avoided
where not required.
* data/bison.m4 (b4_percent_define_use): New.
(b4_percent_define_get): Use it.
Accept a default value.
* data/c++.m4: Do not provide a default value for the %define
variable location_type, rather, use b4_percent_define_get with a
default argument where its value is needed.
* data/lalr1.cc: Do not load location.cc (which outputs both
location.hh and position.hh) if the user defined location_type.
Do not include location.hh either.
* data/glr.cc: Likewise.

zero values in the YYTABLE comments.

* src/tables.h: In header comments, explain why it's useless to
check for a zero value in yytable.
* data/bison.m4 (b4_integral_parser_tables_map): Fix YYTABLE
comments: zero indicates syntax error not default action.
* data/c.m4 (b4_table_value_equals): Comment that YYID must be
defined.
* data/glr.c (yyis_pact_ninf): Rename to...
(yypact_value_is_default): ... this.
(yyisDefaultedState): Update for rename.
(yyis_table_ninf): Rename to...
(yytable_value_is_error): ... this, and check for value zero
besides just YYTABLE_NINF.
(yygetLRActions): Check for default value from yypact. It
appears that this check is always performed before this function
is invoked, and so adding the check here is probably redundant.
However, the code may evolve after this subtlety is forgotten.
Also, update for rename to yytable_value_is_error. Because that
macro now checks for zero, a different but equivalent branch of
the if-then-else here is evaluated.
(yyreportSyntaxError): Update for rename to
yytable_value_is_error. The zero condition was mishandled
before.
(yyrecoverSyntaxError): Update for renames. No behavioral
changes.
* data/lalr1.cc, data/lalr1.java (yy_pact_value_is_default_):
New function.
(yy_table_value_is_error_): New function.
(parse): Use new functions where possible. No behavioral
changes.
(yysyntax_error_, yysyntax_error): Use yy_table_value_is_error_.
The zero condition was mishandled before.
* data/yacc.c (yyis_pact_ninf): Rename to...
(yypact_value_is_default): ... this.
(yyis_table_ninf): Rename to...

The zero condition was mishandled before.

* src/tables.h: Improve comments about yypact, yytable, etc.
more. Most importantly, say yytable value of zero means syntax
error not default action.
This patch simplifies "variables: rename namespace as api.namespace",
commit 6750106107.

http://lists.gnu.org/archive/html/bison-patches/2009-07/msg00006.html
* src/muscle-tab.c (muscle_percent_variable_update): New.
(muscle_percent_define_insert): Use it in replacement of the
previous tr invocation.
Remove variable_tr, no longer needed.
* data/bison.m4 (b4_percent_define_copy_, b4_percent_define_copy):
Remove.
* data/c++.m4: No longer handle namespace -> api.namespace.
* tests/input.at (%define backward compatibility): Check that
namespace is treated as api.namespace.
* data/bison.m4: Move code related to specific variables after the
definition of the variable-maintaining macros so that we don't
"invoke" b4_percent_define_check_values before it is defined.
Implement, document, and test the replacement of %error-verbose
by %define parse.error "verbose".
* data/bison.m4 (b4_error_verbose_if): Reimplement to track the
values of the parse.error variable.
Make "simple" its default value.
Check the valid values.
* src/parse-gram.y: Use %define parse.error.
(PERCENT_ERROR_VERBOSE): New token.
Support it.
* src/scan-gram.l: Support %error-verbose.
* doc/bison.texinfo (Decl Summary): Replace the documentation of
%define error-verbose by that of %define parse.error.
* NEWS: Document it.
* tests/actions.at, tests/calc.at: Use parse.error instead of
%error-verbose.

"api.namespace".
Default the latter to the former.

obsolete.
Document api.namespace.
Use @samp to document %define uses, keep @code for identifiers.

namespace. (The tests passed with namespace.)
