Got the code to compile.
-------------- Build: Release in Cilk Plus (compiler: i586-linux-gnu_gcc4.9)---------------
gcc -Wall -fcilkplus -O2 -m32 -c "/home/stahta01/CB_Work/Intel Cilk Plus/main.c" -o obj/Release/main.o
gcc -L/usr/lib/gcc/i586-linux-gnu/4.9/64 -L/usr/lib/gcc/i586-linux-gnu/4.9 -o "bin/Release/Intel Cilk Plus" obj/Release/main.o -s -m32 -lcilkrts
Output file is bin/Release/Intel Cilk Plus with size 4.98 KB
1. Most important if using GCC 4.9 under Debian 8.0 (64 bit) is to have this package installed g++-multilib
(Likely true for GCC 4.8; likely untrue for GCC 4.7 or older)
2. Need option "-m32" in both compiler and linker other options.
3. Change the linker from g++ to gcc in CB toolchain settings
