Current snapshots of GCC 4.8.0 issue a warning about some of the
new code in windowscodecs/pngformat.c:

  pngformat.c: In function 'PngDecoder_Frame_GetColorContexts':
  pngformat.c:882:5: warning: passing argument 5 of 'ppng_get_iCCP' from
  incompatible pointer type [enabled by default]
     if (ppng_get_iCCP(This->png_ptr, This->info_ptr, &name, &compression_type,&profile, &len))
  pngformat.c:882:5: note: expected 'png_bytepp' but argument is of type 'char **'

The patch below addresses this.
