Bruce,
I've worked a lot with patches, and sometimes it's very hard to spot a
tiny difference (not just trailing spaces or line ending mismatches, for
which you could have simply used the "-l" flag).
What I usually do is take the produced .rej file, edit the "before" part
to get rid of the two leading spaces that patch inserts, and compare it
via diff (or, better yet, vimdiff, as it highlights the *actual* changes,
not just the lines) to the corresponding chunk of the original code.
This approach, of course, is not Cygwin-specific.
HTH,
Igor
