For the moment, I think that we can stick to (1).  This does not prevent us from
reorganizing our module code and tm-define such that TeXmacs works flawlessly
with Guile 3.  This would be a welcome effort anyway, since even if Guile drops
its support for other OSs, then we might need such a reorganization to move to
another Scheme implementation.  After all the trouble we went through to make 
TeXmacs
available on all platforms, I don't think that it is a good long term plan to 
rely
on a library that is limited to only a few platforms, especially for a 
programming
language like Scheme.
