I was just being stupid, misread the original code and did not
realize that the generic code quoted in your log message:
#define get_be32(p) ( \
... byte-at-a-time implementation )
is not limited to big endian boxes [*1*]. So I think the message is
fine as-is.
[Footnote]
*1* In other words, the ntohl(*(uint *)(p)) is used only on selected
little endian boxes, but that does not mean the generic code was
big-endian only. Little endian boxes that are not listed in #if
block do use the generic byte-at-a-time macro.
