I am still having problems with bjam, but from what I can tell these are the commands that should build your example by hand.  Perhaps there is something I am missing about the commands I need to pass to gcc.  

I get the same results with:  g++ -o link example/link.cpp src/asm/fcontext_x86_64_sysv_macho_gas.S src/protected_stack_posix.cpp -I../..

 gcc -c -o fctx.o src/asm/fcontext_x86_64_sysv_macho_gas.S
 g++ -c -o protected_stack_posix.o src/protected_stack_posix.cpp -I../..
 g++ -o link example/link.cpp protected_stack_posix.o fctx.o -I../..
