|       * lib/autoconf/general.m4 (AC_CONFIG_M4_DIR): Stub out a macro
|       that future autopoint/aclocal/automake/autoreconf will be able
|       to trace to find where to install local m4 macros.

Please, install, document and NEWS :) But I would like to departure
from the "m4" presence (if I could change history, these guys would be
.ac too).  I would prefer AC_CONFIG_MACRO_DIR, or
AC_CONFIG_AUTOCONF_DIR etc.  And the variable name needs to be
documented too.
