I use Google. I think I started with "site:cygwin.com inurl:ml patch
textmode" and followed a couple of threads.

Perhaps running u2d afterwards, dunno... You might also try building
patch with textmode.o linked in, but I'm not sure if that would do what
you want.

Probably what happened was patch got confused because it saw CRLF line
endings on the target file but just LF in the patch file, and so
couldn't find any common matching context between them. In the case of
a textmode mount, patch would see LF endings in both the patch and the
target, and so the contexts matched up.
