The binary pretest install does. I'd like to figure out the > difference. Are both binaries in the same directory? Is the libpng DLL on PATH or with one of the binaries? Do you have more than one libpng DLL, one of which might be in conflict with the w64 build, or from a different version of libpng, or lacks its own support libraries? What is the version of libpng whose header files are visible when you build your own Emacs, and are those headers from the same version of libpng as the DLL you have installed? These are some of the reasons that might explain the problem. In general, it's most probably some kind of DLL hell.
