The patch is wrong, you need a libpng.so symlink, and the WINE_CHECK_SONAME regexp will then determine the proper soname.
This is totally wrong. The png lib is named libpng12.so.* and not libpng.so Therefore the check against libpng12.so should be the default...I don't know any distro which ships libpng.so symlink anyhow.
