I get *color counting (-cc option) is not supported* when trying to `pngcrush` with the `-reduce` option. It seems that pngcrush won't do any color-type/bit-depth reduction because of this. According to [this post](http://aur.archlinux.org/packages.php?ID=22877) this can be enabled by adding `+CFLAGS+=	-DPNGCRUSH_COUNT_COLORS` to the makefile.
