RE: Cilk Library

["Iyer, Balaji V" <balaji dot v dot iyer at intel dot com>]

Dear Jeff and the rest of Steering committee members,
     Thank you very much for approving the license terms of the Cilk Library. I couldn't attach the zipped copy of the patch due to its size, so here is a link to the Cilk library patch that can be applied to the trunk: (https://docs.google.com/file/d/0BzEpbbnrYKsSWjBWSkNrVS1SaGs/edit?usp=sharing).

     Is it OK for trunk?

Here are the ChangeLog entries:

ChangeLog:
2013-10-09  Balaji V. Iyer  <balaji.v.iyer@intel.com>

        * Makefile.def: Add libcilkrts to target_modules.  Make libcilkrts
        depend on libstdc++ and libgcc.
        * configure.ac: Added libcilkrts to target binaries.
        * configure: Likewise.
        * Makefile.in: Added libcilkrts related fields to support building it.
