----------------------------+--------------------------
 After an update to Xcode (version 8) on OS X 10.11.6 I found that my
 projects won't build due to 'OSMemoryBarrier being deprecated.  I tried to
 rebuild the library with the new tools and found that it won't build
 either due to the same error.
