Actually GNU software is supposed to be portable to traditional make.
The only reason this hasn't been noticed before is that most
traditional 'make' programs don't warn about the misuse of $<.  I
installed this patch to fix the problem, along with another one I
noticed at the same time.

2004-03-03  Paul Eggert  <address@hidden>

        * bin/Makefile.am (edit): Don't use $< in a context where
        POSIX doesn't require support for it.  Use address@hidden instead.
        Problem reported by Anthony N. Frasso in
        <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
        * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
