Hmhm. Does anyone see if and how we could turn this into a more
generic `_check_type' function? Something like:

  local type

  _check_type type $words[1] ... # args?

  case $type in
  GNU) ...
  AIX) ...
  *)   ...
  esac

Would that be possible withou making _check_type too expensive?

Bye
 Sven
