Rich,

The "binmode" setting in the CYGWIN environment variable only affects
writes to pipes.  For disk writes, Cygwin consults the mount table.
Check your mounts (using the "mount" command), and make sure the directory
that contains the input/output file of "patch" is mounted in text mode.
If it isn't, use the "mount" command again to re-mount it.
	Igor
