still having problems with xemacs 20.4 on netbsd/alpha 1.3...

looks like a few header files are missing...
unexalpha.c:35: filehdr.h: No such file or directory
unexalpha.c:36: aouthdr.h: No such file or directory
unexalpha.c:37: scnhdr.h: No such file or directory
unexalpha.c:38: syms.h: No such file or directory

anyone have any suggestions?
