[boost] Boost Filesystem v3 - requires wstring - an obstacle to testing the serialization library

The boost serialization library test suite uses Boost.Filesystem in 
order to build and run it's tests.  Turns out that the tests under mngw 
fail to build with the following message:

In file included from ..\libs\serialization\test\test_tools.hpp:10,
                  from ..\libs\serialization\test\test_binary.cpp:24:
../boost/filesystem/operations.hpp:21:5: #error Configuration not 
supported: Boost.Filesystem V3 and later requires std::wstring support
In file included from ../boost/filesystem/operations.hpp:24,

So it seems that Boost.Filesystem requires support for wstring and mngw 
doesn't support it - so the serialization library tests can't run.

Does anyone have any ideas for an expedient way to work around this?
