GCC 4.3 now warns about "a || b && c" and asks for explicit
parentheses.
Reported by Alexandre Duret-Lutz.
* data/location.cc: Update copyright years.
(Position::operator==): Use parens to make precedence explicit.
Compare lines and columns first, as they are more likely to be
different, and they are faster to compare.
Grep on Solaris does not support -q.
Reported by Summum Bonum.
* NEWS: Add a stub for 2.4.2.
* THANKS: Add Summum Bonum.
* tests/atlocal.in (EGREP): New.
(CC, CXX, XSLTPROC): Make it possible to override them via
envvars.

where the underlying implementation changed.
* tests/cxx-type.at (_AT_RESOLVED_GLR_OUTPUT)
(_AT_RESOLVED_GLR_OUTPUT_WITH_LOC, _AT_AMBIG_GLR_OUTPUT)
(_AT_AMBIG_GLR_OUTPUT_WITH_LOC, _AT_GLR_STDERR)
(_AT_VERBOSE_GLR_STDERR): Expand to double-quoted strings,
since some of them contain unbalanced ')'.

announcements already, not 1.4.3, which breaks the build.
We're thinking of extending it's effect on output file naming. See the
thread at
<http://lists.gnu.org/archive/html/bison-patches/2008-10/msg00003.html>.
* NEWS: Say it's experimental.

recommend it over %skeleton for now.

(Java parser class extends and implements): New test.
Model exception propagation better with throws and lex_throws.
* data/java.m4 (b4_list2): New.
(throws): Change default.
* data/lalr1.java (yyaction): Add throws.
(parse): Add lex_throws in addition to throws.
* doc/bison.texinfo (throws, lex_throws): Add documentation.
* tests/java.at (Java throws specifications): New test.
Improve documentation for Java parsers.
* doc/bison.texinfo (Java Parsers): Add subsections.
Don't quote first argument of %define.

features that error out. Document directives with no effect.
Move note about Javadoc higher.
(Java Semantic Values): Explicitly mention stype.
Document that generic types cannot be used.
(Java Location Values): Use @deftypeivar. Document constructors.
Correct return value for toString.
(Java Parser Interface): List undocumented constants/fields.
Move documentation of fields added by %parse-param closer to list
of members. Document that token names are added as fields.

Interface. Describe %code lexer and yylex accutately.
Remove documentation that does not match the code.
(Java Action Features): New.

2008-10-27 Di-an Jan <dianj@freeshell.org>
* data/lalr1.jave: Update copyright years.
(YYParser): Correct name of "generated from" file in Javadoc:
use b4_file_name instead of @ofile@.
(Location constructor): Correct Javadoc parameter name.
(yylloc): Add missing opening m4 quote after b4_location_if.
This removes a stray [ in the Javadoc of Lexer.getStartPos.
(Lexer.yyerror): Fix incorrect m4 and Javadoc.
(YYParser constructor): Correct Javadoc parameter name.
* src/files.c (compute_file_name_parts): When the user specifies
--output but not --file-prefix, extract the directory prefix from the
file prefix not from the grammar file name. This affects the location
of files like location.hh generated by the C++ skeleton. The includes
in the other output files require this fix.
* tests/output.at (AT_CHECK_OUTPUT): Automatically create directories
for expected output files.
(Output files): Add a test for the above.
* data/lalr1.cc (debug_stream, set_debug_stream)
(debug_level_type, debug_level, set_debug_level): Don't
declare them when YYDEBUG is not defined.
The implementation are already YYDEBUG-aware.
* HACKING (Administrivia): Make the git-merge-changelog notes more
helpful.

(Release Procedure): Update for git and add numerous details that were
previously missing.
* Makefile.am (EXTRA_DIST): Remove Makefile.cfg and Makefile.maint.
* maint.mk (announcement): Don't list bison as a bootstrap tool so
that announcements don't claim we bootstrapped with whatever bison
happened to be in PATH. Add flex as a bootstrap tool.
* Makefile.maint: Remove, previously replaced by maint.mk.
* Makefile.cfg: Remove, and migrate settings to...
* cfg.mk: ... here for the sake of `make announcement'.
* bootstrap.conf (gnulib_modules): Add announce-gen.
* README: Say GNU Bison instead of just Bison. Suggested by Karl
Berry.
2008-10-08 Di-an Jan <dianj@freeshell.org> (tiny change)
