For compiled operational function detail::copy_file, pass detail::copy_options, a plain-old enum, rather than a BOOST_SCOPED_ENUM. We cannot pass a BOOST_SCOPED_ENUM to a compled function because it will result in an undefined reference if the library is compiled with -std=c++0x but the use is compiled in C++03 mode, or vise versa. Fixes tickets #6124, #6779, and #10038.
