Yes, gnofract4d 3.12 does. See #28089.
The libpng ChangeLog (http://www.libpng.org/pub/png/src/libpng-1.2.x-to-1.4.x-summary.txt 
) documents this:
2. b. We removed the typecasted NULL definitions such as

         #define png_voidp_NULL    (png_voidp)NULL

      If you used these in your application, just use NULL instead.
