If you have downloaded the tcsh sources from cygwin/contrib/tcsh,
you have the changes incorporated. There's no hint to Cygwin itself
but you will find many places with sth. like


	#ifdef O_TEXT
	  setmode (fd, O_TEXT);
	#endif

or the same for O_BINARY.

Roughly spoken the bin/textmode patch is doing usually the same
in all shells:

O_TEXT mode for:
	- stdin
	- script files
	- here scripts
	- backquote commands
	- the `read' command

O_BINARY mode for:
	- pipes

Leave it as it is for:
	- stdout, stderr and their redirection

(no demand for completeness)

Hope, that helps,
Corinna
