Hmm, OK. I've tried this again booting off a Knoppix Linux CD and the diff /
patch over the CRLF files on the FDD worked fine, applying the patch and
preserving the CRLF. This does seem to be something weird with the way
Cygwin is dealing with the files.
Thanks,
Rich

All,
Sorry, no joy - same outcome
Here's my mount :
drb398 AT net251 /
$ mount
C:\cygwin\usr\X11R6\lib\X11\fonts on /usr/X11R6/lib/X11/fonts type system
(binmode)
C:\cygwin\bin on /usr/bin type system (binmode)
C:\cygwin\lib on /usr/lib type system (binmode)
C:\cygwin on / type system (binmode)
a: on /mnt/foo type system (textmode)
c: on /cygdrive/c type user (binmode,noumount)
I've used the a: drive as the location for patching, just to keep it
separate from other mounts. I recreated the patch file using diff on the
textmode mount point, just to be sure. My patch file and the target source
code files were all under /mnt/foo (a:). I used 'mount -t a:/ /mnt/foo' for
the mount.
Thanks
Rich

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
