coders/png.c missing declaration when QuantumDepth=32

[rmagick]

Trying to build ImageMagick 6.3.3-1 with QuantumDepth=32, I get this message from make:

/bin/sh ./libtool --silent --tag=CC --mode=compile gcc -DHAVE_CONFIG_H -I. -I./magick -I./wand -I/usr/include/freetype2 -I/usr/X11R6/include -I/usr/include/libxml2 -g -Wall -W -pthread -MT coders/coders_png_la-png.lo -MD -MP -MF coders/.deps/coders_png_la-png.Tpo -c -o coders/coders_png_la-png.lo `test -f 'coders/png.c' || echo './'`coders/png.c

Thanks for the problem report. We will have a fix for this problem in the next point release.
