+       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.
+       (%error-verbose, %pure-parser): No longer tokens.
+       * src/scan-gram.l (pure-parser): Return as a %<flag>.

+
+       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.

+       Regen.
+       * src/parse-gram.h, src/parse-gram.c: Regen.

+
+       Factor %FLAG at scan level.
+       * src/parse-gram.y (PERCENT_DEBUG, PERCENT_ERROR_VERBOSE): Token
+       definitions and associated rules, replaced by....
+       (PERCENT_FLAG): this new token type, and rule.
+       * src/scan-gram.l (RETURN_PERCENT_FLAG): New.
+       Use it for %debug and %error-verbose.
