And failing that there's always dos2unix, or even:

   $ tr -d '\015' < oldfile > newfile

IME the biggest problem with DOS-format files is with scripts run using
the '#!<interpreter>' syntax on the first line.  Having extraneous CRs
at the end of such lines can just get you a "bad interpreter" error
message when you try to run the script.
