Hmmm.  The following patch seems to improve my system a little bit.  But
I'm not certain if they are correct.

Looks like, for autom4te.in, maybe the process SHOULD be automated.  Or at
least made possible for a sanity check before shipping.  Without that
update, the stuff in /usr/share/autoconf/autoscan also contains
AC_DECL_SYS_SIGLIST, which was a bit confusing at first.
