Sean, IIRC one of the guys at Monta Vista was the one that did the
initial SQLlite
support patch for rpm.  IIRC he dealt with some endian issues
there...but my memory is always fuzzy with things I am not directly
working on so I could be very wrong.  Course maybe with SQLlite there
just arn't any such issues.
