 The main idea is to save the current Emacs state as C source code, then com= pile the (large and boring) .c file and relink Emacs with the resulting .o = file instead of a dummy .o file that it would start off with. Most of this = new .o file would be data; perhaps some would be code that would initialize= the data, though we'd want to minimize this.


I find it disturbing that a C c= ompiler will be needed to redump Emacs.
