That patch was for CVS HEAD. I guess you tried to apply it to 4.1.18?

That's my theory too.

I don't know, but what version of Make are you using? There was an earlier
report of the same problem from someone using MinGW's Make with MSVC.
Apparently, this bug is present in version 3.79, but fixed in 3.80. Maybe
you can get a newer version of Make for Cygwin?
