* Fix Windows build of Jaeger tests The Jaeger tests use the low-level syscall package. The Windows specific function called in that package has a different function signature than the unix version. Add a windows specific file using the build flags to isolate this OS specific functionality. * Add changes to changelog * Blind succeed to account for unimplemented functionality on Windows
