I don't think that pretending would be actually helpful for the user.
Even if it would make it easier to build a project using duetto, then
the user would need to track errors at runtime. On the other hand if
fstream is completely not supported the user will be notified by the
compiler on each use. I think that the point should not be to build a
C++ project without modification, but building a C++ project that
actually works with minimal modifications.
