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

Hello Jason et al.,
	Mike Stump mentioned that my _Cilk_spawn and _Cilk_sync for C++ may have been lost in the email pile. So, attached is an updated _Cilk_spawn and _Cilk_sync for C++ patch. Is this Ok to install?

Here are the ChangeLog entries (they shouldn't have changed since the last submission):
