+
+ Enable the Java related testsuite tests when the only Java compiler
+ found is a gcj < 4.3. Discussed at
+ <http://lists.gnu.org/archive/html/bug-bison/2007-02/msg00016.html>.
+ * configure.ac (gt_JAVACOMP): Don't specify a target_version.
+
+2007-02-11 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * data/Makefile.am: Update copyright date.
+ * data/push.c (yypull_parse): Report memory exhaustion and return 2 if
+ yypstate_new returns NULL.
+ (yypstate_new): Return NULL if malloc does.
+ * src/reader.c (packgram): Move translation of rule actions from the
+ beginning of packgram to...
+ (check_and_convert_grammar): ... here right before packgram is invoked
+ so it's easier to write more complete comments, and remove redundant
+ code.
+
+2007-02-10 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ As in semantic actions, make @$ in %initial-action, %destructor, and
+ %printer imply %locations.
+ * src/scan-code.l (SC_SYMBOL_ACTION): Set locations_flag = true when
+ scanning @$.
+ * tests/actions.at (AT_CHECK_ACTION_LOCATIONS): New macro supporting...
+ (@$ in %initial-action implies %locations,
+ @$ in %destructor implies %locations,
+ @$ in %printer implies %locations): ... these new test cases.
+

+
+ Undo most of the 2007-02-03 change, switching to the strcase module
+ now that gnulib strcase has been fixed.
+ * bootstrap.conf (gnulib_modules): Remove c-strcase. Add strcase.
+ * lib/.cvsignore: Remove c-ctype.c, c-ctype.h, c-strcase.h,
+ c-strcasecomp.c, c-strncasecmp.c. Add strcasecmp.c, strncasecmp.c
+ * m4/.cvsignore: Add strcase.m4.
+ * src/getargs.c: Revert 2007-02-03 change, as follows.
+ Don't include c-strcase.h.
+ (language_argmatch): Use strcasecmp rather than c_strcasecmp.
+ strcasecmp has "unspecified behavior" outside the POSIX locale,
+ but it works fine in practice if at least one argument is ASCII,
+ as is the case in Bison.
+
+2007-02-07 Paolo Bonzini <bonzini@gnu.org>
+
+ * tests/java.at: Skip tests if only one of javac/java is present.
+ Reported by Joel E. Denny.
+ * tests/atlocal.in: Adjust copyright years.
+
+2007-02-05 Paolo Bonzini <bonzini@gnu.org>
+
+ * data/lalr1.java (Stack): Work around old verifiers that disallow
+ access to the private fields of an inner class, from the outer class.
+ We can make Stack's fields public because user code doesn't have access
+ to the instance of Stack used by parse(). Reported by Paul Eggert.
+
+2007-02-03 Paul Eggert <eggert@cs.ucla.edu>
+
+ * .cvsignore: Add javacomp.sh, javaexec.sh. Is this really
+ the right spot for these files?
+ * bootstrap.conf (gnulib_modules): Add c-strcase.
+ * lib/.cvsignore: Add c-ctype.c c-ctype.h, c-strcasecomp.c,
+ c-strncasecmp.c.
+ * src/getargs.c: Include c-strcase.h.
+ (language_argmatch): Use c_strcasecmp rather than strcasecmp,
+ to avoid unspecified behavior.
+
+2007-02-01 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * doc/bison.texinfo (Decl Summary): Correct typo.
+
+2007-01-30 Paolo Bonzini <bonzini@gnu.org>
+
+ * data/bison.m4 (b4_percent_define_flag_if): Don't treat 0 as false.
+ Complain if the value does not match empty, "true" or "false".
+ * data/c++.m4: Adjust default definitions of %define variables.
+ * data/java.m4: Adjust default definitions of %define variables.
+ * doc/bison.texinfo (Decl Summary): Adjust the %define entry according
+ to above behavior.
+ * tests/input.at (Boolean %define variables): Test new behavior.
+
+2007-01-29 Paolo Bonzini <bonzini@gnu.org>
+
+ * NEWS: Mention java.
+ * TODO: Remove things that are done.
+ * bootstrap.conf: Add javacomp-script and javaexec-script.
+ * configure.ac: Invoke gt_JAVACOMP and gt_JAVAEXEC.
+
+ * data/Makefile.am: Add new files.
+ * data/java-skel.m4: New.
+ * data/java.m4: New.
+ * data/lalr1.java: New.
+
+ * doc/bison.texinfo: Put "A Complete C++ Example" under
+ C++ Parsers. Add Java Parsers. Put C++ Parsers and Java Parsers
+ under Other Languages.
+
+ * src/getargs.c (valid_languages): Add Java.
+ * src/getargs.h (struct bison_language): Update size of string fields.
+
+ * tests/Makefile.am: Add java.at.
+ * tests/atlocal.in: Add CONF_JAVA and CONF_JAVAC.
+ * tests/java.at: New.
+ * tests/testsuite.at: Include it.
+
+2007-01-28 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up.
+ * src/scan-skel.l (at_directive_perform): Add at_directive_argc and
+ at_directive_argv arguments so these no longer have to be global
+ variables. Also, update the implementation for the following changes.
+ (fail_for_at_directive_too_many_args,
+ fail_for_at_directive_too_few_args): Add at_directive_name argument.
+ (at_directive_name): Remove as at_directive_argv[0] will be used for
+ this now.
+ (AT_DIRECTIVE_ARGC_MAX): Increment to make space in at_directive_argv
+ for the directive name.
+ (at_directive_argc, at_directive_argv): Make these local within
+ skel_lex instead of global.
+ (INITIAL): Update directive start action for above changes.
+ (SC_AT_DIRECTIVE_ARG): Rename to...
+ (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.
+ (SC_AT_DIRECTIVE_SKIP_WS): Update.
+ (scan_skel): Move yylex_destroy to...
+ (skel_scanner_free): ... here.
+ * tests/skeletons.at (installed skeleton file name): Rename to...
+ (installed skeleton file names): ... this.
+
+2007-01-27 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * ChangeLog: For changes in doc/bison.texinfo, consistently reference
+ node names: say "Table of Symbols" not "Bison Symbols", and say "Decl
+ Summary" not "Directives".
+ * doc/bison.texinfo (Decl Summary, Calc++ Parser): Cross-reference the
+ %code entry in "Decl Summary" rather than the one in "Table of Symbols"
+ since the former is now the more complete one.
+ (Prologue Alternatives): Likewise and do the same for %defines.
+ (Table of Symbols): Add summary of %code, add summary of %define, and
+ move full %code documentation to...
+ (Decl Summary): ... here for consistency with other entries in these
+ sections.
+ Move %define entry in order to keep this list alphabetized.
+ Reword %define entry a little to put less emphasis on the skeleton
+ concept, which most users shouldn't have to think about.
+
+2007-01-26 Paul Eggert <eggert@cs.ucla.edu>
+
+ Adjust to recent gnulib changes.
+ * lib/.cvsignore: Remove stpcpy.h, strndup.h, strnlen.h.
+ Add string.h, string_.h, unistd_.h, wchar_.h.
+ * m4/.cvsignore: Add gnulib-common.m4, string_h.m4, wchar.m4.
+ * src/system.h: Don't include <stpcpy.h>; this is now done by
+ <string.h>.
+
+2007-01-23 Paolo Bonzini <bonzini@gnu.org>
+
+ Simplify implementation of unqualified %code, implement macros for
+ uniform treatment of boolean %define flags. Document %define.
+ * data/bison.m4 (b4_percent_define_ifdef, b4_percent_define_flag_if,
+ b4_percent_code_ifdef): New.
+ (b4_percent_code_get): Map unqualified %code to b4_percent_code().

in the yychar entry.
In the yychar entry, remove mention of the local yychar case (pure
parser) since this is irrelevant information when writing semantic

isn't when semantic actions are deferred.
