My suggestion is to remove the whole attribute construct (see attached).
It only suppresses a warning when a function is unused. In this case
the function is defined as inline, so it's not causing a warning when
not used.
With the attached patch, the code compiles without errors or warnings
on FreeBSD/ia64.
FYI,
