Huhh. My impression was, that these are rather old system calls, which
do exist for long time now [1] and there is just another -l$lib
statement missing. If the kfreebsd port exposes some functions in the
header files, but finally does not implement it in any library I'd call
that a bug. Would it make sense to file a bug against the kfreebsd port?
