1) IPython/core/compilerop.py: IronPython __future__ flags are non-standard, Solution try/except; comment added 2) IPython/core/completer.py: __main__ was undefined, due to local mistake in creating IronPython scope; removed this tweak 3) IPython/core/prompts.py: os.getuid() is not defined (IronPython bug; see: https://mail.python.org/pipermail/ironpython-users/2014-February/016812.html) 4) IPython/lib/inputhook.py: ctypes SystemError; comment added 5) IPython/utils/process.py and IPython/utils/_process_cli.py: adds a new _process_cli.py which would handle the processes under cli; fixed os.pathsep 6) IPython/utils/io.py: devnull opened in append mode; changed to "w" 7) New issue: IPython/external/decorator/_decorator.py: IronPython doesn't have _getframes, unless FullFrames is set to true; comment added
