Now the autoconf generated files are no longer in the source in libpng18
AM_MAINTAINER_MODE is not required; the generated files must have the
correct timestamp.
This change is essential in a development environment where "git pull"
may update configure.ac, Makefile.am because NOW the pull does not
update configure and Makefile.in as well. This solves a lot of problems
but not when AM_MAINTAINER_MODE is in configure.ac where it just creates
a complete mess; configure and Makefile.in don't get updated and
mysterious (to the puller) build failures happen.
Note that 'configure --enable-maintainer-mode' is incompatible with
doing builds for different architectures in parallel; it ends up with
two configure processes overwriting stuff in ${srcdir}.
To generate a tarball run configure with "--disable-maintainer-mode".
See the discussion in paragraph 5 of section 26.2.2 of the GNU automake
manual (1.7.4).
