OK, so how about this:

  -Map=<file>   Put the map into <file>.  <file> can be relative or absolute.
  -Map=<dir>    Put the map into <dir>/basename (outfile).map.  Overwrites existing maps.
  -Map=%        Put the map into (outfile).map.  Includes all path components in (outfile)

Would this work for you ?

Cheers
