Origin: backported from ESP Ghostscript CVS
Description: Fix configure bug related to libpng detection. See
    http://www.cups.org/str.php?L396. As a side-effect, this patch exposes a
    bug on the compilation of gdevpng.c. A workaround is to compile the
    shared library using the "make CFLAGS_SO='-fPIC $(ACDEFS)' so" command.
    See http://www.cups.org/str.php?L602 for more details. Note that this
    patch modifies the configure.ac file, so you need to run "autoconf" to
    rebuild a fixed configure script.
