Please forgive me if this has already been answered - I joined the list today and have found no solution to my problem in the archive. I can't build 21.2-b2 under NT, I could build 21.2-b1 with no problems. Here's the output of my nmake command (I removed dired.obj and filelock.obj before doing the nmake).
