Neither does OpenBSD.  And POSIX doesn't seem to mention it either.
So this smells like a Linux-specific extension.  Or perhaps more
accurately, a glibc-specific extension.  So you should change the
#ifdefs around I think.  Or perhaps go the protable route using
fileno(3) and fcntl(2).  I don't think atomicity is a real requirement
here.
