question re V1 toolset

While testing the serialization library DLL version with gcc 3.3 I get
duplicate symbols on link:

The link command line looks like the folllowing. Note that the libraries are
all included twice. ?

"g++"
"-Wl,--enable-auto-image-base"
-g
-o
"c:\BoostMainCVS\bin\boost\libs\serialization\test\test_binary_binary_archiv

gcc\debug\boost_serialization-gcc-d-1_32.lib"
-lboost_serialization-gcc-d-1_32

Is this intentional? Could this be the source of the duplicate symbols
error messages? Is there a way to address this?
