Nope, none that I'm aware of.

Yes, that might help.

That's just the way the source package does it-- you can 'make UISTYLE=text'
or 'make UISTYLE=gtk2' and both give unison.exe.??But?you're?right,?of
course I can change the names.

Sure, that would work.??Maybe?just?a?shell?wrapper?that?checks?if?DISPLAY?is
set and runs either unison-text.exe or unison-gtk2.exe.

I don't think I want to go that far in modifying the source, especially
since it's written in OCaml, which I don't know and have no other need to
learn.??But?a?shell?wrapper?would?take?care?of?it.
