 Thanks to mrg, I discovered that rev 1.9 (-current) of xf86atomic.h
 fixes the above issue.  Continuing on with rev 1.9, I then get to this
 In file included

 <tr1/unordered_set> ^
 1 error generated.
 nbmkdep: compile failed.
 Not sure what the right fix is, other than 'grab newer sources'.  
 -current xsrc seems to work much better, but I end up with this:
