Here is a reproducible script

$ mkdir old
$ mkdir new
$ cat >old/file
Line1
Asdf
Line2
^D
$ cat >new/file
Line1
Fdsa
Line2
^D
$ diff -u old new >1.tm
$ patch <1.tm

The last command gives the error

can't find file to patch at input line 4
Perhaps you should have used the -p or --strip option?
The text leading up to this was:
--------------------------
|diff -u old/file new/file
|--- old/file   2005-09-30 08:15:00.796875000 -0600
|+++ new/file   2005-09-30 08:16:18.796875000 -0600
--------------------------
File to patch:

If then you simply enter old/file at the prompt, then patch works.  This is
a clear indication that there is a problem with the tool's interpretation of
a windows path.

This is not a case of "I don't know how patch works."  I have been using
patch for a long time.  It is simply not working.

What error message are you getting that you think is not right?  Did you
use the -p option?  We need a reproducible test case.  Also, it may help
to follow these directions:
