[Boost-build] Attempting to build 32 bit Linux library on 64 bit OS

I'm using CENTOS and gcc 3.4.6.

My environment is:
export PATH=`pwd`/tools/jam/src/bin.linux:$PATH
export CFLAGS=-m32
export CXXFLAGS=-m32
export LDFLAGS=-m32

I then run ./configure
Then bjam cxxflags=-m32 linkflags=-m32 cflags=-m32 architecture=x86 address-model=32 -d2 debug

I have two issues, first is that some files generate errors stating: "LONG_BIT definition appears wrong for platform (bad gcc/glibc config?)." from /usr/include/python2.3/pyport.h.  This error prevents some of the libraries from building.

2nd, the libraries that do get generated don't make it to a central library directory, but instead all remain in a library specific subfolder.  For example, the date time library is generated in: libs/date_time/build/gcc-3.4.6/debug/address-model-32/architecture-x86/libboost_date_time-gcc34-d-1_34_1.so.1.34.1

First, I'd like to ask, is there a released build that gives me the 32 bit libraries?
Second, assuming there isn't, is this possible to generate a 32 bit library on a 64 bit Linux system?
Third, if so, what am I doing wrong?  Thank you for your help.
