Never mind.  I was looking wrongly at toplevel configure.ac rather than
fixincludes/configure.ac.

But you still need to help it a bit, because aclocal won't find the
definition of AC_PROG_SED itself.  You can just add
  m4_sinclude(../libtool.m4)  dnl needed for AC_PROG_SED

as the first line to fixincludes/configure.ac.  That should be
sufficient.

Cheers,
Ralf
