+       * src/getargs.h, src/getargs.c (locations_flag): Remove.
+       * src/getargs.c, src/scan-code.l: Use muscle_percent_define_ensure
+       to set "locations" to true.
+       * src/output.c (prepare): Don't output "locations".
+       * src/scan-gram.l (%locations): Handle it as a %<flag>.
+       * src/parse-gram.y: It's no longer a token.
+       Don't handle it.
+       * data/bison.m4 (b4_locations_if): Define it with
+       b4_percent_define_if_define.

+       muscle: factor the handling of obsolete of obsolete directives.
+       Suggested by Joel E. Denny.
+       
+       * src/muscle_tab.h, src/muscle_tab.c (muscle_percent_define_ensure):
+       New, extracted from...
+       * src/parse-gram.y (prologue_declaration: pure-parser): here.
+       Remove it.
+       (prologue_declaration: "%<flag>"): Use
+       muscle_percent_define_ensure.

+       Fix options documentation.
+       * build-aux/cross-options.pl: As in --help output, write optional
+       arguments as [=ARG] not =[ARG].
+       * doc/bison.texinfo (Bison Options): Add -W/--warnings argument.

+
+       Replace BISON_PROG_GNU_M4 with Autoconf's AC_PROG_GNU_M4.
+       If the first m4 in $PATH is wrong, it keeps looking.  Moreover, its
+       requirements for a correct m4 are stricter.
+       * m4/m4.m4: Make it a symbolic link to submodules/autoconf/m4/m4.m4.
+       * configure.ac: Update to use AC_PROG_GNU_M4.
+       Reported by Eric Blake.

+       Help with updating web manual.
+       * HACKING: Incorporate instructions from gnulib/doc/README.
+       * bootstrap.conf (gnulib_modules): Add gendocs.
