Thanks for the award :-)

I agree that it's not strictly an endian problem. I first discovered it when
comparing the results for some public-domain MD5 code between a SPARC
machine (big-endian) and an Intel machine (little-endian), and so the
problem has been tagged "endian" in my brain ever since.

I'm crossing my fingers...
