* src/getargs.h, src/getargs.c (skeleton_arg, language_argmatch):
The location argument is now mandatory.
Adjust all dependencies.
(getargs): Use command_line_location.
* src/getargs.c (quotearg.h, muscle_tab.h): Include.
(getargs): Define file_name.
* src/main.c (main): Initialize muscle_tab before calling
getargs.
* src/muscle_tab.c (muscle_init): No longer define file_name, as
its value is not available yet.
* build-aux/cross-options.pl: The argument ends at the first
space, not the first non-symbol character.
Use @var for each word appearing the argument description.
* data/lalr1-fusion.cc (yydestruct_): Invoke the variant's
destructor.
Display the value only if yymsg is nonnull.
(yyreduce): Invoke yydestruct_ when popping lhs symbols.
This is used to help the user catch cases where some value gets
ovewritten by a new one. This should not happen, as this will
probably leak.
Unfortunately this uncovered a bug in the C++ parser itself: the
lookahead value was not destroyed between two calls to yylex. For
instance if the previous lookahead was a std::string, and then an int,
then the value of the std::string was correctly taken (i.e., the
lookahead was now an empty string), but std::string structure itself
was not reclaimed.
This is now done in variant::build(other&) (which is used to take the
value of the lookahead): other is not only stolen from its value, it
is also destroyed. This incurs a new performance penalty of a few
percent, and union becomes faster again.
* data/lalr1-fusion.cc (variant::build(other&)): Destroy other.
(b4_variant_if): New.
(variant::built): New.
Use it whereever the status of the variant changes.
* etc/bench.pl.in: Check the penalty of %define assert.

<http://lists.gnu.org/archive/html/bug-bison/2008-11/msg00001.html>.
* THANKS (Sergei Steshenko): Add.
* src/scan-code.l (SC_RULE_ACTION): Fix it.
* tests/regression.at (Fix user actions without a trailing semicolon):
New test case.
* etc/bench.pl.in (&run, &generate_grammar): New.
Rename the grammar generating functions for consistency.
Change the interface so that the list of benches to run is passed
as (optionless) arguments.
(&compile): Use &run.
* data/lalr1-fusion.cc (b4_symbol_variant): Adjust additional
arguments.
(variant::build): New overload for
copy-construction-that-destroys.
(variant::swap): New.
(parser::yypush_): Use it in variant mode.
std::list cannot be copied via memcpy, they are more demanding than
std::string. Use one std::list to strengthen the test.
* examples/variant.yy: Use lalr1-fusion.cc, not lalr1.cc.
Adjust.
Create a list of strings, instead of a single large string.
* data/bison.m4 (b4_copyright): Fix the indentation of the
copyright year paragraph.
Use b4_copyright_years when no years are given.
* data/lalr1.cc, data/lalr1-fusion.cc, data/location.cc
(b4_copyright_years): New.
Use it.
* doc/bison.texinfo (calc++.cc): Propagate failures to the exit
status.
* examples/calc++/test ($me, $number, $exit, run): New.
Use them to propagate errors to the exit status.
* etc/bench.pl.in (variant_grammar): Fix the computation of
$variant.
Generate a grammar file that can work with or without %debug.
Do use the @directive.
(bench_variant_parser): Check impact of %debug.
(@directives): Rename all the occurrences to...
(@directive): this, for consistency.
* etc/bench.pl.in: More doc.
Some fixes in the documentation.
($cflags, $iterations, &help, &getopt): New.
Use them.
(&variant_grammar): Let the number of stages be 10 times what is
specified.
* etc/bench.pl.in ($cxx, &variant_grammar, &bench_variant_parser):
New.
(&compile): Be ready to compile C++ parsers.
(&bench_push_parser): Move debug information to the outermost
level.
* THANKS: Add Michiel De Wilde.
* etc/bench.pl.in (&directives): New.
(&triangular_grammar, &calc_grammar): Use it to format the Bison
directives.
(&triangular_grammar): Do use the directives (were ignored).
(&bench_grammar, &bench_push_parser): Adjust to pass lists of
directives.
