What exactly are the requirements? Making GOption "just work" when it
is used on Windows the same way it is on Unix is impossible.

Your Dia problem was different from bug #522131, because you
apparently don't use GOption. I fixed the "some filenames don't open"
bug in Inkscape a long time ago; the whole point is that the fix
prevents me from using GOption.

If this is possible using some IPC mechanisms already wrapped by GLib,
I guess the GLib IPC could be used. Otherwise use named pipes or file
mappings (aka shared memory). I'm not sure whether named pipe creation
has the same useful semantics as named mutex creation.
