Re: Emacs on GNUstep

There is a crash on startup.  It might be a fault in the Emacs code, or 
in Art, but I stopped looking once I noticed it worked in xlib, since 
there were a lot of other issues to work on...  ;)

I had heard that.  Partly for this reason, I think it may make things 
easier to clean up the existing codebase before trying the move to 21.  
There is a fair amount of accumulated cruft from the transitions over 
the years through OpenStep, Rhapsody, and OS X.  For instance, there 
are major sections of code that aren't even used (but might have been 
switched out for Rhapsody yet work better under GNUstep than what IS 
used right now.)

Actually, I should have added that PC already supports Emacs pretty 
nicely through gnuclient/gnuserv.  The only advantage that would come 
with ns-emacs is that there are a number of methods already implemented 
in it for things like going to a particular line in a file, ready for 
DO access.  (Actually gnuclient can support a lot of this too but going 
through DO would be cleaner.)  An embedded panel implementation might 
also be possible, though possibly not as easy as it sounds.
