Alexandre suggests in
http://www.winehq.org/pipermail/wine-devel/2009-February/073288.html
that it would be ok for the loader to check the version of the native
dll with the version of the builtin one, and use the native one if higher.

A few links related to version checking:
http://msdn.microsoft.com/en-us/library/yw3yyscd(VS.80).aspx
http://www.codeproject.com/KB/cpp/UpdateVersion.aspx 

(Here are some messy notes about retrieving resources from inside ntdll.
actctx already does this kind of thing, so looking there for ideas is probably
good.
    hModule = LoadLibraryExW(filename, 0, LOAD_LIBRARY_AS_DATAFILE);
      // -> use LdrGetDllHandle instead in ntdll?
    hRsrc = FindResourceW(hModule,
                          MAKEINTRESOURCEW(VS_VERSION_INFO),
                          MAKEINTRESOURCEW(VS_FILE_INFO));
      // -> use LdrFindResource_U  instead in ntdll?
    len = SizeofResource(hModule, hRsrc);
    hMem = LoadResource(hModule, hRsrc);
      // LdrAccessResource in ntdll?
    buf = LockResource(hMem);
    vffi = (VS_FIXEDFILEINFO *)VersionInfo32_Value( (VS_VERSION_INFO_STRUCT32
*)buf );
    verify that ( vffi->dwSignature == VS_FFI_SIGNATURE )
    access vffi->dwFileVersionMS and vffi->dwFileVersionMS
    FreeResource(hMem);
)
