Agreed, it's not impossible. It just won't happen with gretl on 
Windows and Mac unless/until we cross-build the Lua Library, build 
gnuplot linked against Lua, and include Lua in our package.

The only other way it could happen is if Windows users build or 
somehow acquire a Lua-enabled wgnuplot.exe themselves and substitute 
it for the one we package.
