Hmm, I wonder why I did not see it when I tried it. I once did a find to see
whether "cilk.h" was installed - but the find turned up blank. I now do see
several cilk/ include files - including cilk.h. :-(

Probably the right choice is to simply revert r208440.

What do you mean by this? I have a pending - and hopefully more sensible -
patch at http://gcc.gnu.org/ml/gcc-patches/2014-03/msg00492.html where
-fcilkplus implies -lcilkrts [-pthread], but I am not sure whether that's what
you meant.
