Think different. Think of linking mentioned application against
xlibs/gtk+/whatever. Then, if(getenv("DISPLAY")) you could init the X11
client side. This way, you can work on console (using so far Linux'isms)
_and_ you can work under X11 within _one_ binary. What now is the point
is to fetch all the events which are ment to out xterm's window.

So, if you're running on console (!getenv("DISPLAY")), you initialize
your input routine using ioctl(), but if running under X11, you
initialize needed xlibs. The remaining problems then is to fetch the
right events. I currently see no easy way in doing this, but there of
course must be some:-}
