1) For the boost 1.39, we can compile 32-bit boost library using following command:

$ ./bjam -a address-model=32 architecture=x86 variant=debug threading=multi link=shared runtime-link=shared

the most important flag is: "address-model=32 architecture=x86", if only set the address-model to 32, the gcc compiler still can't compile 32bit library. we must also set the architecture to x86
