png is the default graphics format for preview-latex
<URL:http://www.gnu.org/software/auctex/preview-latex.html>.  It is
not uncommon for users to report problems with selfcompiled Emacs

I don't mind being able to specify --without-libpng and/or
--without-libgif, but the default behavior makes it somewhat too easy
to overlook that one is not generating a fully-capable Emacs for a
given platform.
