Tried it..

It doesn't work.. But not for the reasons that are displayed for 
Stephen. It doesn't get as far as attempting to link it fails to build 
the regex library before that. All of the errors are of this kind:

    Error : illegal initialization
             (instantiating: 
'boost::cpp_regex_traits<char>::get_mutex_inst()')
../../../boost/regex/v4/cpp_regex_traits.hpp line 1011  static 
static_mutex s_mutex = BOOST_STATIC_MUTEX_INIT;

Possibly a config issue? OK.. a bit of investigation.. After 
preprocessing that line looks like (+context):

template <class charT>
static_mutex& cpp_regex_traits<charT>::get_mutex_inst()
{
static static_mutex s_mutex = { {0x32AAABA7, {}}, } ;
return s_mutex;
}

[Note.. having two identical files: boost/regex/static_mutex.hpp, and 
boost/regex/pending/static_mutex.hpp is a really nasty thing to do. 
Spent some time trying to figure out why my changing one has no effect 
on the compile.]

Looking further up if I change the static_mutex implemention as such:

Index: boost/regex/pending/static_mutex.hpp

Then the regex lib compiles, and the test passes.

So we are down to the differences between Stephen's setup of 
OSX-10.3/CW-9.3 and mine of OSX10.2/CW-8.3.
