+In addition the order of the png_get_uint macros with respect to the relevant
+function definitions has been reversed.  This helps the preprocessing of the
+symbol files be more robust.  Further the symbol file preprocessing now uses
+-DPNG_NO_USE_READ_MACROS; this stops the read macros interfering with the symbol
+file format.
