Problem with checksum failing on large files

	His original post showed that this happens acrossed various
operating systems with matching versions (2.5.2 and 2.5.5 matched up, and
then 2.5.2 and 2.5.5 mismatched, over SunOS and AIX).

	Could you try to reproduce this under Linux and MS-Windows?
Considering that they are very large files, I'm wondering if it's not
something in the way the O.S. reads the large files...(?)

	Perhaps you could mail this code to Terry, so he can test to see
if it fixes the problem.  If not, then we know it's not the broken
checksum implementation.  But if so, we've found the bug.

	That is, assuming Terry has enough time to volunteer into
