+### Please describe the problem.
+
+Thanks for the improvements in Windows long file support but it turns out that Git-annex
+commit 54ad1b4cf doesn't quite compile on Windows without a small fix to Remote.Git and
+Utility.DirWatcher.Win32Notify regarding imports.
+
+### What steps will reproduce the problem?
+
+`stack setup && stack build`
+
+### What version of git-annex are you using? On what operating system?

+### Have you had any luck using git-annex before? (Sometimes we get tired of reading bug reports all day and a lil' positive end note does wonders)
+
+Git Annex is great. I use it several times a week with my multigigabyte backups, where it gives structure to my image-based backup routines, so you could say I'm a believer. :)
