OK, so libcilkrts will not configure properly without libstdc++.i686 in 
the system .. so somewhere in the configury magic its falling back on 
the system  libstdc++ library, and won't work without it.

My little test program worked fine when I added
export 
LD_LIBRARY_PATH=/gcc/2013-10-31/build/x86_64-unknown-linux-gnu/32/libstdc++-v3/src/.libs:/gcc/2013-10-31/build/./gcc/32/

to pick up the 2 shared libraries... so I presume  LD_LIBRARY_PATH needs 
to be set by your configure stuff in order to work.


You should be able to test this by uninstalling libstdc++.i686 ona 64 
bit machine and configuring.  I didn;'t have it, and when I did add it, 
everything works fine.
