Hi

Building today shows libpng has changed upstream. In consequence one of 
the patches in

  libpng-1.2.43-apng.p needs omitting as code it patches isn't there 
like that any more:

@@ -2159,8 +2252,8 @@
  #ifndef PNG_WRITE_WEIGHTED_FILTER_SUPPORTED
    if (png_ptr->row_number == 0 && filter_to_do == PNG_ALL_FILTERS)
    {
-      /* These will never be selected so we need not test them. */
-      filter_to_do &= ~(PNG_FILTER_UP | PNG_FILTER_PAETH);
+      /* These use previous row */
+      filter_to_do &= ~(PNG_FILTER_UP | PNG_FILTER_AVG | PNG_FILTER_PAETH);
    }
  #endif

If this hasn't yet been caught, and you can replicate it, could it 
please be put into the autobuilder?

hanks

John
