It is inaccurate and uncharitable to call that automake work
short-sighted.  The problem is that development on that front seems to
have stalled.  Since that part of automake is incomplete, if you don't
know the history, I can see how you would think it short-sighted.
It is, of course, a good thing that gnulib-tool is filling the gap.

Thanks for working on that.
However, that change breaks coreutils' build-from-bootstrap process:

    doc/Makefile.am:21: installing `build-aux/texinfo.tex'
    lib/gnulib.mk:21: automatically discovered file `alloca.c' should not be 
explicitly mentioned
    lib/Makefile.am:20:   `lib/gnulib.mk' included from here
    lib/gnulib.mk:21: automatically discovered file `error.c' should not be 
explicitly mentioned
    lib/Makefile.am:20:   `lib/gnulib.mk' included from here
    lib/gnulib.mk:21: automatically discovered file `lstat.c' should not be 
explicitly mentioned
    lib/Makefile.am:20:   `lib/gnulib.mk' included from here
    lib/gnulib.mk:21: automatically discovered file `obstack.c' should not be 
explicitly mentioned
    lib/Makefile.am:20:   `lib/gnulib.mk' included from here

I'm using this fix:

2006-11-13  Jim Meyering  <address@hidden>

        * gnulib-tool (func_get_automake_snippet): Don't emit into a *_SOURCES
        definition any of the names that automake includes automatically:
        alloca.c, error.c, lstat.c, obstack.c.
