autoreconf doesn't honor m4_include

[Werner LEMBERG]

[autoconf 2.69]

[groff's top-level configure script doesn't use automake, libtool, or
 autopoint]


Unpack groff-1.22.1.tar.gz and say

  autoreconf -i

at the top level.  You get the following two warnings:

  configure.ac:120: warning: macro 'AM_ICONV' not found in library
  configure.ac:138: warning: macro 'AM_LANGINFO_CODESET' not found in library

However, there is a top-level `aclocal.m4' file which looks like this:

  m4_include([m4/iconv.m4])
  m4_include([m4/localcharset.m4])
  ...

It's necessary to say

  autoreconf -i -I m4

to avoid the warnings.  This looks like a bug.
