Bummer; as I re-read my email I see that I didn't express myself well at
all. I agree that systems exchanging information should always use the
routines in question (even though I didn't explicitly state that) ... my
point about "no conversion necessary" was in response to Steve
Carpenter's assertion that the functions "did nothing" on big-endian
machines. Even though the functions do nothing, they should still be
used for portability.
Sorry about that!
