Yes, it compiles, links, and runs for me as well.  Getting back to basics
has isolated the problem I am having.  The client code which uses copy_file
is compiled using MainWin, implements the Win32 API, and defines _WIN32,
WIN32, etc.  So the Boost.Filesystem code from the headers is compiling with
BOOST_WINDOWS_API defined.  However, the Boost.Filesystem library was
compiled with GCC natively (i.e. without MainWin), so it has BOOST_POSIX_API
defined.  These clearly cannot work together.

Thanks for the help and suggestions, Beman, I really appreciate it.  This
has been puzzling me for some time.  I'm glad that we have found the
problem.
