[boost] Pointer-based streams, and a minor link problem

I just added a boost/io/pointer_stream.hpp file to the sandbox, with related
files in the "libs" section.  The streams use a begin/end pointer pair to
define a buffer, using the default handling of std::basic_streambuf to do
the most of the work.

I have a problem with one of my linkings.  I have a Mac OS X 10.2 system
with Project Builder (GCC 3.1 based) and CodeWarrior (Pro 8.3 based).  The
test program compiles on PB and the non-debug version compiles on CW, but
the debug version on CW gives the following link error:

//========================================================================
Link Error   : multiply-defined:
'@_ZN5boost12test_toolbox6detail23equal_and_continue_implIPcA0_cEEbRKT_RKT0_
RNS_17wrap_stringstreamEPKciNS_19unit_test_framework9log_levelE$picbase'
(code)
Defined in pointer_stream_test.cpp
Defined in pointer_stream_test.cpp

//========================================================================

Are the (debugged) mangled names of two items so long that the
distinguishing parts are cut off?  Is this just a hiccup, to be resolved by
a restart?  Or could this be a plain ol' bug?
