[Boost-users] trouble compiling with -m32 or address-model=32

I'm trying to build boost_1_34_0 on an x86_64 linux box with a 32-bit
address model.

After letting configure create a bjam for me, I have tried many
variations on the following:

 tools/jam/src/bin.linux/bjam address-model=64 -d2 release

And also:

 tools/jam/src/bin.linux/bjam cxxflags=-m32 linkflags=-m32 cflags=-m32
-d2 release

The -d2 appears to show me what the compiler is doing.  I see no sign
of -m32 command-line options when the compiler is invoked.  I also
checked the .so file that was created and verifited that it's
dynamically linked to libraries in /lib64.

What am I doing wrong??

Here's some of the -d2 output with address-model:
