Bootstrapping the 'next' branch fails for me with:

  Don't forget to
    - "include gnulib.mk" from within "lib/Makefile.am",
    - mention "-I m4" in ACLOCAL_AMFLAGS in Makefile.am,
    - mention "m4/gnulib-cache.m4" in EXTRA_DIST in Makefile.am,
    - invoke gl_EARLY in ./configure.ac, right after AC_PROG_CC_STDC,
    - invoke gl_INIT in ./configure.ac.

      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
  autoreconf2.50: /usr/bin/autoconf failed with exit status: 1

The same happens if I apply your patch on master.  Weird.

More info that might be useful:

But the same failure happens with autoconf 2.69 installed from the tarball.
