First, you'll have to put the Makefile in 'unix mode', i.e. put the
hallmark line

	SHELL=/bin/sh

in it. This will cause DJGPP make to use DJGPP bash as the shell for
command execution, instead of command.com.

Then something like

       grep --quied --binary `echo -e "\r"` foo.bar && dtou foo.bar

would do. OTOH, I honestly can't see the use for such a command.  dtou
works on Unix text files, too, leaving them unchanged.  I.e. the check
is not strictly necessary, IMHO.
