Any more progress on OS X native Aqua XEmacs?

I believe there are some readers of this mail list who were working on a native port of XEmacs to Mac OS X. There is currently (as of this week) an Aqua port of GNU Emacs (21.3.50.6). I wondered whether any of the folks working on the XEmacs port had looked at it or examined the source to see if any of it could help with porting XEmacs 21.5 to native Aqua OS X? One real advantage I have seen is that the native port uses about 50MB less of physical memory because XFree no longer needs to be loaded. The disadvantage is that it is not XEmacs--a rather large disadvantage. r. royar
