Re: [bug-gnulib] using AC_LIBSOURCES: complementing the `Files:' section

[Karl Berry]

    The goal of my proposal to add uses of AC_LIBSOURCES was to make the
    m4->[.c,.h] dependency-tracking tighter and cleaner.  Also, it helps
    packages (that don't use gnulib-tool) avoid distributing incomplete sets
    of portability-related files.

FWIW, these basic points seem sound to me.

Autoconf already provides the functionality, so why not use it, instead
of reimplementing it in gnulib-tool?  Unless I'm misunderstanding the
situation ...
