+ * July 8, 2005
+ * There was a bug in the calculating code of the Fletcher32
+ * checksum in the library before v1.6.3. The checksum
+ * value wasn't consistent between big-endian and little-endian
+ * systems. This bug was fixed in Release 1.6.3. However,
+ * after fixing the bug, the checksum value is no longer the
+ * same as before on little-endian system. We'll check both
+ * the correct checksum and the wrong checksum to be consistent
+ * with Release 1.6.2 and before.
