+
+ Undo my 2007-02-07 change, switching back to the c-strcase module
+ introduced in the 2007-02-03 change. Bruno Haible reported that
+ the 2007-02-07 change would be dangerous in Turkish if we add a
+ language whose name contains "i", since "i" is not lowercase "I"
+ in Turkish.
+ * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase.
+ * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h,
+ c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c.
+ * m4/.cvsignore: Remove strcase.m4.
+ * src/getargs.c: Revert 2007-02-07 change, as follows.
+ Include c-strcase.h.
+ (language_argmatch): Use c_strcasecmp rather than strcasecmp.
+
+2007-02-11 Bruno Haible <bruno@clisp.org>
+
+ 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.
+
+2007-02-07 Paul Eggert <eggert@cs.ucla.edu>
+
+ 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.
