[boost] building 32-bit boost on an AMD Opteron?

From: chrisc_at_[hidden]

Hi -- I am trying to build boost on a 64-bit AMD Opteron but make it yield 
32 bit code. The reason for this is I want smaller executables and memory 
footprint (Side note: if you do pmap on even a small hello world program 
on an 64 bit Opteron it requires 10 MB of virtual memory vs. 1.2 MB if 
compiled in 32 bit mode -- Can you believe it?).

I have tried to edit the tools/build/gcc-tool.bjam file to add the -m32 
compiler option to LINKFLAGS, CFLAGS, CPPFLAGS and CXXFLAGS. However, in 
doing so, it generates a number of compiler errors.

Below is a sample (I am using GCC 4.0.2 under SUSE Linux).

Any help would be most appreciated!!

thank you!,
Chris

skipping Boost.Python library build due to missing or incorrect 
configuration

couldn't find Python.h in "/usr/local/include/python2.2"

You can configure the location of your python installation by setting:
PYTHON_ROOT    - currently "/usr/local"
PYTHON_VERSION - The 2-part python Major.Minor version number (e.g.
                  "2.2", NOT "2.2.1")  - currently "2.2"

The following are automatically configured from PYTHON_ROOT if not
otherwise set:

     PYTHON_LIB_PATH       - path to Python library object; currently
                             "/usr/local/lib/python2.2/config"
     PYTHON_INCLUDES       - path to Python #include directories; currently
                             "/usr/local/include/python2.2"
