+	* Makefile.def: Add libcilkrts to target_modules.  Make libcilkrts 
+	depend on libstdc++ and libgcc.
+	* configure: Regenerate.
+	* configure.ac: Added libcilkrts to target binaries.  Also, restrict
+	libcilkrts for POSIX and i*86, and x86_64 architectures.
+	* Makefile.in: Added libcilkrts related fields to support building it.
