-## Description: add some description

-## Bug: bug URL
-Description: Avoid usage of F_DUPFD_CLOEXEC where not available (e.g. kfreebsd*)
-  The patch is mostly taken from 10_kfreebsd-f_dupfd_cloexec.patch (gnome-terminal)
-  Bug-Debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=711529
-  Description: Fix build on kfreebsd
-  
-  kfreebsd doesn't have F_DUPFD_CLOEXEC, so use it conditionally.
-  As mentioned in the bug report, it will have support for it in
-  jessie, so we can drop it in jessie+1
