File::Copy also provides the syscopy routine, which copies the file specified in the first parameter to the file specified in the second parameter, preserving OS-specific attributes and file structure. For Unix systems, this is equivalent to the simple copy routine, which doesn't preserve OS-specific attributes (ed: emphasis added). For VMS systems, this calls the rmscopy routine (see below). For OS/2 systems, this calls the syscopy XSUB directly. For Win32 systems, this calls Win32::CopyFile.

At least it was put in the small print ;-(
