From: Michael Gooch Date: Thu, 12 Jan 2017 16:21:42 GMT Subject: problem with insider build for windows and git Message-ID: <1bddbd50-86ea-6c38-6ab8-08336de2ba72@gmail.com> when running commands like pull and clone I get the following message: Cygwin WARNING: Couldn't compute FAST_CWD pointer. This typically occurs if you're using an older Cygwin version on a newer Windows. Please update to the latest available Cygwin version from https://cygwin.com/. If the problem persists, please see https://cygwin.com/problems.html Windows build is version 1607, OS BUILD 15002.1001 I assume they broke something that cygwin was depending on.
