I looked at them. The most serious change I can find is:
-     png_error(png_ptr, "PNG unsigned integer out of range.\n");
+     png_error(png_ptr, "PNG unsigned integer out of range.");

and
-void /* PRIVATE */
+void PNGAPI
 png_save_uint_16(png_bytep buf, unsigned int i)


Also, some exports were only conditionally enabled by
-#if defined(PNG_READ_pCAL_SUPPORTED) || defined(PNG_READ_oFFs_SUPPORTED)



So, this seems safe to me.

Andi
