(octave starts compiling, but I don't see any MAKE_BUILTINs rolling by 
the screen; Array-i.cc and so on are compiling but I've yet to see a 
libinterp/builtin-defun-decls.h file, then...)

Somewhere along the way

libinterp/builtins.cc
libinterp/octave.df
libinterp/oct-conf.h
libinterp/version.h

builtin_defun_decls.h is empty:

The contents of builtin-defun-decls.h now has a partial list that 
includes "Fwarning", hence the previous error no longer is an issue.

OK, those .df files don't look good.

rm -f */*.df
rm -f */*/*.df
make
(Now I see all the -DMAKE_BUILTINS commands stream by.)
cat */*/*.df
(All the .df files look good...compilation successful.)
