Hi,
While trying to port the current swift code to FreeBSD, some swift code fails
to compile. The failures are concentrated in SwiftPrivatePthreadExtras.swift
and code which depends on it.
Can someone shed some light on the following errors? I am having some
difficulty understanding why the C headers would be interpreted so slightly
differently than expected?
--(start compile failure)

error: cannot convert value of type 'UnsafePointer<pthread_attr_t>?' to
expected argument type 'UnsafePointer<pthread_attr_t?>!'
let result = pthread_create(&threadID, attr,

Thanks for any suggestions or pointers!
