--- Comment #2 from Eric Blake <eblake at redhat dot com> ---
'unsigned short' promotes to 'int', not 'unsigned int', when passed through
var-args. The warning is technically correct, but annoying, since all values
of 'unsigned short' are representable in both 'int' and in 'unsigned int',
therefore %d vs. %u won't ever have to deal with a negative value.
"%u" with signed 'short' should indeed warn, because that is a case where
promotion to 'int' differs from printing unsigned values.
"%x" with 1 should indeed warn, because that is passing 'int'. Use "%x" with
1U if you want to avoid the warning.
