buffer's file over last processed file.

Handle isc 4.1 operating system.

instead of direct access to the save_modiff field.

All callers now use `mail-personal-alias-file'.

Use globally in place of hardwired "~/.mailrc".

and command line option processing.

(VALBITS, GCTYPEBITS): Define these regardless of NO_UNION_TYPE.
[!NO_UNION_TYPE] (union Lisp_Object): Use symbolic constants.

Use them instead of direct access to save_modiff field.

(struct buffer): New fields begv_marker, zv_marker.

(struct buffer): Make text field be a pointer.
The struct buffer_text field renamed to own_text.
Add fields indirect_to_buffer and size.
Move pt, begv and zv fields here.
