Description
Harmony won't compile with libpng 1.4, released on january . Some bleeding edge distros have changed to libpng 1.4 [Gentoo and ArchLinux] and other will probably follow. Basically what affect the compilation is the use of png_infopp_NULL which is now depreceated and should use NULL instead. After changing this to NULL everything works fine.
