on AT&T 3B* there were:

filehdr.h
aouthdr.h
scnhdr.h
reloc.h
syms.h
storclass.h

(at least according to the document I have).

emacs' coff unexec includes one of coff.h, coff-encap/a.out.encap.h, a.out.h

I am of the opinion that:

a) there should be a single header, multiple headers seems like overkill to
me.
b) coff.h is more descriptive, but there obviously is precedent for a.out.h
including coff information.
c) there  appears to be variation from machine to machine, so whatever is
decided is probably not going to conform to something or other.

If a.out.h is agreeable to everyone then call it a.out.h. Its certainly no
less obvious what it is for than coff.h.

Can you let me know of your decision since I will have to change XEmacs.

cheers,

andy
