+Platforms that do not have rdev, blksize, or blocks will return these
+as '', so numeric comparison or manipulation of these fields may cause
+'not numeric' warnings.

mtime and atime are the same thing, and ctime is creation time instead of
inode change time. (S<Mac OS>)
mtime, atime and ctime all return the last modification time. Device and
inode are not necessarily reliable. (S<RISC OS>)
+dev, rdev, blksize, and blocks are not available. inode is not
+meaningful and will differ between stat calls on the same file. (os2)

=item symlink OLDFILE,NEWFILE
Not implemented. (Win32, VMS, S<RISC OS>)
