Re: configure dependencies, and version.texi dependencies (PR/358).

| Does this mean Autoconf should use absolute paths?

| % autoconf -f -i -tm4_include:'$1' /dev/null
| m4sugar/version.m4
| autoconf/autoupdate.m4
| autoconf/general.m4
| autoconf/status.m4
| autoconf/autoheader.m4
| autoconf/autotest.m4
| autoconf/programs.m4
| autoconf/lang.m4
| autoconf/c.m4
| autoconf/fortran.m4
| autoconf/functions.m4
| autoconf/headers.m4
| autoconf/types.m4
| autoconf/libs.m4
| autoconf/specific.m4
| autoconf/oldnames.m4

Stupid me.  Filtering on the *location* on the m4_include should
suffice.
