I don't see on pkgbox yet.

Also I didn't past the earlier warning for above:

cc -std=gnu99  -I.      -O2 -MT freadahead.o -MD -MP -MF 
. deps/freadahead.Tpo -c -o freadahead.o freadahead.c
freadahead.c: In function 'freadahead':
freadahead.c:83: warning: implicit declaration of function '__sreadahead'

What is the way to handle this for older DragonFly?
(Why isn't __sferror defined like it is on other BSDs?)
