You'll need to provide more detail about the failure.  What's the error
message?  Is there an error message?  Can you get the exact command line
that patch is generating and execute it manually?

Not likely.  I use Cygwin and NT4 and ClearCase 4.2 at work all the time.
No problems interacting with each other.  However, things to watch out
for are path specifications.  If your patches uses "\" for the directory
separator, and that's what's being passed in the command, then most
likely the "\" is being treated as an escape character.  This is
especially true if patch is executing the command from a sub-shell (in
which case the *shell* is doing the interpreting, not cleartool).

Time like this require some debugging output at the place where the
command is being executed.  You've got the source for patch, so go to it!
