[boost] [iostreams] file_descriptor::read bug?

In the source libs/iostreams/src/file_descriptor.cpp, file_descriptor::read,
line 147, I think

  return static_cast<std::streamsize>(result);

should be

  return static_cast<std::streamsize>(result == 0? -1: result);

The Windows API ReadFile returns TRUE with result == 0 when it has come to
end-of-file.
