Comment (by Fernando Diaz <fdiaza@…>):

 I see. In any case, am I correct in seeing

 {{{__sync_fetch_and_add( pw, -1 );}}}

 and

 {{{__sync_fetch_and_sub( pw, 1 );}}}

 as interchangeable? Because if the change is correct, but cannot be
 incorporated into boost, I  could keep it on my side and reapply it each
 time boost is updated.
 Thanks!
