+
+       * src/getargs.c (valid_languages): Add Java.
+       * src/getargs.h (struct bison_language): Update size of string fields.

+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.

+       skel_lex instead of global.

+       (SC_AT_DIRECTIVE_ARG): Rename to...
+       (SC_AT_DIRECTIVE_ARGS): ... this, and update for above changes.

+
+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.

+       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().
