Comment (by redwoodtree@…):

 Found the same issue after upgrade to mac os Sierra and Xcode 8.  Found
 that /usr/local/include/pthread.h appears to have an undeclared type on
 line 423 with the "Swift unavailable message".  Workaround was to copy the
 file to /opt/local/include/pthread.h and comment out line 423:
 /*__SWIFT_UNAVAILABLE_MSG("Use lazily initialized globals instead") */

 Will file a bug with apple.
