If the only place that this is used is in DisplayGraph then it’s probably safe to simply #ifdef it out for Windows Mobile.  That API is intended to only be used when debugging, and the kind of debugging environment doesn’t really make sense for a mobile device that doesn’t have the debugger / toolchain running locally.  It would probably be worth modifying DisplayGraph to dump the contents of the .dot file in the debugger, when it is not possible to run other programs.
