Milestone:  To Be Determined  |   Component:  filesystem

------------------------------+---------------------------------------------
 The compiled part of Boost.FileSystem v3 uses scoped enums in its
 interface. This is the case with the copy_file function. This creates
 linking incompatibilities if Boost is compiled in C++98 and user's code in
 C++11 mode because in the former case scoped enums are emulated and thus
 generate a different name in the decorated function names. It's worth
 noting that typically binary distributions of Boost in Linux are built in
 C++98 mode, which complicates linking C++11 user's code.

 The suggested fix is to use either integers or traditional enums in the
 private library interface.
