+### Please describe the problem.

+aws 0.16 has a breaking change, causing git-annex' usage of S3.UploadPartResponse to fail.

+### What steps will reproduce the problem?
+
+Try to build git-annex with aws 0.16.
+
+### What version of git-annex are you using? On what operating system?
+
+Not sure, I got this build failure report from ilovezfs who I think uses Max OS X, and git-annex master.
+
+### Please provide any additional information below.

+[[!format sh """
+# If you can, paste a complete transcript of the problem occurring here.
+# If the problem is with the git-annex assistant, paste in .git/annex/daemon.log

+# End of transcript or log.

+
+### 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)
