[Boost-users] boost::filesystem with wstring

Hello,
I am using Boost 1.41.0 with Visual Studio 2005 and noticed some strange behaviour which I am unsure how to fix.

When I call boost::filesystem::remove_all("somepath");
everything compiles and links fine.

But now a project works entirely on wstring basis so it happens that I pass something like 

boost::filesystem::remove_all(L"somepath");

Code compiles still fine but it throws many linker errors like

Fehler	2	error LNK2001: nresolved external symbol ""__declspec(dllimport) class boost::filesystem::file_status __cdecl boost::filesystem::detail::status_api(class std::basic_string<unsigned short,struct std::char_traits<unsigned short>,class std::allocator<unsigned short> > const &,class boost::system::error_code &)" (__imp_?status_api_at_detail@filesystem_at_boost@@YA?AVfile_status_at_23@ABV?$basic_string_at_GU?$char_traits_at_G@std@@V?$allocator_at_G@2@@std@@AAVerror_code_at_system@3@@Z)".

So what happens here? I searched boost for some wstring support or similar but had no luck.
It is quite unhandy to transform to and from wstring<>string.

Thanks
