Windows boost::filesystem canonical on NTFS network drives mounted in a directory

When on Windows, if you use boost::filesystem::canonical() to resolve a 
NTFS network drive mounted in a directory, the result is what I see as a 
useless result.  For example:

C:\ntfs_mount\other\dirs\file

boost::filesystem returns:

C:\?VolumeXXX-XXX-XXX-XXX\ other\dirs\file

This volume notation is useless as it cannot be passed to any file 
function.  Also, the path is divided by a space to other\dirs.  It would 
be better if canonical does not mess with the network drive at all and 
returns the directory as is, like boost::filesystem::absolute() does.
