fs::copy fails with FILE_ATTRIBUTE_REPARSE_POINT attribute

Description
Platform : Windows 7 64bits
When using fs::copy on a regular file with Windows APL attributes (Archive, sparse file, reparse point), fs::copy returns error code BOOST_ERROR_NOT_SUPPORTED.
When passing though the fs::copy, the "from" file is not detected as a regular file walking to the "else" case.
With a little investigation, file status reports our file as a reparse file because of the REPARSE_POINT attribute.
Is this behaviour the expected one ? knowing that a direct call to fs::copy_file works.
Note:
See TracTickets
for help on using tickets.
The failure is explained in my recent email on the boost mailing list.
The problem is copy_file only copies regular files and directories, and reparse files should be treated as regular files (in my opinion).
See email for arguments.
