The Hydra buildfarm provides code coverage analysis. For some reason,
in some test cases, code coverage data seem to be incompatible, and
generate error messages at parser run-time. Ignore these messages so
that (i) these tests do pass, (ii) coverage results be provided by
Hydra.
* tests/local.at (AT_PARSER_CHECK): Ignore messages for failed merges
of code coverage/profiling results.
lalr1.cc used to support yyo, but not yyoutput. Support both,
but document only yyoutput (at least until there is some consensus
on this).
* data/c.m4 (yy_symbol_value_print): Also support yyo.
* data/glr.cc (yy_symbol_value_print_): Support both yyo and yyoutput.
* data/lalr1.cc: Also support yyoutput.
* doc/bison.texinfo: Explicitly use yyoutput in the examples.
* examples/mfcalc/mfcalc.test: Test the -p option.

* doc/bison.texinfo (Printer Decl): New.
Number mfcalc.y snippets so that they are output in
the proper order.
(The mfcalc Main): Use yydebug.
(Debugging): Simplify the text.
(Enabling Traces, Mfcalc Traces, The YYPRINT Macro): New.
(Table of Symbols): Document YYPRINT and YYFPRINTF.

* tests/input.at: Use "print" in %printer instead of "destroy".
It is unused, so we don't care, yet it is less surprising.
* tests/actions.at: Comment changes.
(cherry picked from commit abcd36ca1b)
* m4/flex.m4 (_AC_PROG_LEX_YYTEXT_DECL): Check that $LEX
supports some of the Flex options, and exclusive start conditions.
Define FLEX to 'yes'/'', as AC_PROG_CC does for GCC.
* TODO (Documentation, %printer, Java): Remove, already done (or just
waiting for approval).
(Fortran, BTYacc): Remove, there does not seem to be demand.
* bootstrap.conf (bootstrap_sync): True again.
It was disabled while waiting for changes to be integrated
in gnulib's bootstrap, which was done long ago.
* bootstrap, gnulib: Update.
http://lists.gnu.org/archive/html/bison-patches/2012-04/msg00006.html
* doc/bison.texinfo: Avoid using @def* variant with more
than the defined entity as main entity, as it results in
an incorrect index. For instance, don't document
{return YYERROR;}, which results in a single index entry
"return YYERROR;", but rather as typed function whose
return type is "type", and whose argument list is ";".
* data/location.cc (position::initialize, location::initialize):
Also accept line and column, with default values.
* doc/bison.texinfo (C++ position, C++ location): New nodes.
Describe more thoroughly these classes.
Fix several Texinfo misuses.
* data/location.cc (position::position): Accept file, line and
column as arguments with default values.
Always qualify initial line and column literals as unsigned.
(location::location): Provide convenience constructors.

data/location.cc
When the test suite runs with -O2 and warnings enabled, G++
complains of locations being used, but not initialized.
The simplest is to not use locations.
* data/glr.c (b4_locuser_formals, b4_locuser_args): New.
Use them when locations should not be used.
Use b4_locations_if where appropriate.
(yyuserAction): Modify the order to the arguments to make
it more alike the other routines, and to make use of
b4_locuser_args simpler.
C++11 introduces "nullptr" which plays the role of C's NULL, in
replacement of "0". Fix the C++ skeletons to avoid warnings about
uses of "0" in place of "nullptr", and improve C skeletons to also use
this "nullptr" when compiled with a C++11 compiler.
* configure.ac: More C++ warnings.
* NEWS (2.5.1): Document this.
* data/c++.m4, data/c.m4 (b4_null_define): New.
(b4_null): Use YY_NULL instead of 0.
* data/glr.c, data/lalr1.cc, data/location.cc, data/yacc.c:
Call b4_null_define/b4_null where appropriate.
Use YY_NULL instead of NULL.
* data/location.cc (initialize): Accept a default argument,
YY_NULL.
* tests/actions.at, tests/calc.at: Adjust.
* data/glr.c, lib/libiberty.h, src/system.h (__attribute__):
Do not disable it when __STRICT_ANSI__ is defined, as, for
instance, it disables the __attribute__((unused)) which
protects us from some compiler warnings.
This was already done elsewhere in Bison, in 2001, see
4a0d893695.
* tests/regression.at: Adjust output.
* configure.ac (warn_common, warn_c, warn_cxx): New.
Use them to compute independently the options supported
by the C and C++ compilers.
Don't AC_SUBST the variables passed to gl_WARN_ADD: it
does it for us.
(WARN_CFLAGS_TEST, WARN_CXXFLAGS_TEST): Don't aggregate
$WARN_CFLAGS and $WARN_CXXFLAGS in them now, leave it
to atlocal.in.
(O0CFLAGS, O0CXXFLAGS): Move their definition to...
* tests/atlocal.in: here.
Be more systematic between C and C++.
Reorder to factor between variables.
Propagate all of the variables when --compile-c-with-cxx.
* tests/local.at: Go for colors.
(--compile-c-with-cxx): New option.
We used to pass "CC=$CXX" as command line argument,
but it was not possible to adjust CFLAGS accordingly
in atlocal, since it is loaded before assignments on
the command line are honored (so that the command line
takes precedence).
* tests/atlocal.in: Implement it.
* tests/local.mk: Use it.
(cherry picked from commit ac3f2e33b4)
Conflicts:
tests/local.mk
* doc/bison.texinfo (Language and Grammar): Use the same
layout for an example in all the versions, i.e., keep
as general case what used to be used only for Info.
(cherry picked from commit 1d280c0999)
* doc/bison.texinfo: Convert all @smallexamples into @examples.
Adjust layout where needed.
(cherry picked from commit c93f22fcf7)
Conflicts:
doc/bison.texinfo
* doc/bison.texinfo: Avoid line width issues with TeX.
Upgrade ancient messages.
Move some comments to better looking places.
Add more @group.
(Mfcalc Symbol Table): Reduce variable scopes.
Prefer size_t for sizes.
Prefer declarations with an initial value.
Fix a @group environment.
(cherry picked from commit aaaa2aaef4)
Conflicts:
doc/bison.texinfo
* doc/bison.texinfo: Do not use @verbatim, in particular when
we use @group inside.
Use @quotation instead of @display for frequently asked questions,
it looks much nicer.
