Umm... why have you done this?

| $ man clear

Odd. I see

Perhaps you have customised this?

:-)

Alternatively you might like to read http://www.khngai.com/emacs/cygwin.php -
"When the "clear" command is entered into the bash shell, it is expected
to clear the entire shell buffer. However, this does not work for bash
shell under Gnu Emacs. The following lisp statements solve the problem."

(Note: I haven't actually tried the indicated elisp, but my point is
that this does not really seem to be a Cygwin problem, rather an emacs
one... if it is really a problem at all. If the suggeted solution
doesn't work there are more emacs specific lists where you would
probably be better off asking.)
