Problems have been encountered because some of the source files have execute permission set. This can cause git to report them as changed when they are checked out onto a file system with inherited permissions. This has been seen using Cygwin, MinGW and PowerShell Git. This patch makes no change to source file content, and only aims to correct the file modes/permissions.
