Re: LyX/Mac-1.3.5 -- reverse DVI search?

The source code for late versions of LyX/Mac-1.3.3 and for 1.3.4 was 
patched to allow reverse DVI search with MacDviX or recent versions of 
xdvi.  LyX/Mac-1.3.5 needs the same patch (included below) for reverse 
DVI search to work.
Does anyone know what the status of reverse dvi searching on the Mac is 
for 1.4.0? (Trying to apply Ronald's patch for 1.3.x -- see below -- 
fails in 1.4.0.)
