Hi there,

I'm attempting to build boost on Snow Leopard (Mac OS X 10.6). If I  
perform the standard commands i.e something like:

./bootstrap.sh --with-libraries=signals,thread
sudo ./bjam install

then all appears well EXCEPT the libraries are built with a 64 bit  
architecture. That's understandable
given Snow Leopard but I need backward compatibility and hence 32 bit  
libraries. So if I then use:

sudo ./bjam address-model=32_64 install

or

sudo ./bjam address-model=32 install

I get errors. Specifically:

darwin.compile.c++ bin.v2/libs/signals/build/darwin-4.2.1/release/ 
address-model-32_64/link-
static/threading-multi/trackable.o
In file included from ./boost/config/select_stdlib_config.hpp:17,

                from ./boost/type_traits.hpp:13,
                from ./boost/signals/trackable.hpp:13,
                from libs/signals/src/trackable.cpp:12:
/usr/include/c++/4.2.1/cstddef:50:28: error: bits/c++config.h: No such  
file or directory

as the first error. Here's a few more samples:

/usr/include/c++/4.2.1/iosfwd:45:29: error: bits/c++locale.h: No such  
file or directory
/usr/include/c++/4.2.1/iosfwd:46:25: error: bits/c++io.h: No such file

/usr/include/c++/4.2.1/ext/atomicity.h:40:30: error: bits/ 
atomic_word.h: No such file or directory

I note that gcc has been updated and probably remains untested with  
boost. The Snow Leopard version
option yields:

Any suggestions?
