Extended name table.

Normally archives support only 14-character filenames.

Intel has extended the format: longer names are stored in a special element (the first in the archive, or second if there is an armap); the name in the ar_hdr is replaced by <space><index into="" filename="" element>="">. Index is the P.R. of an int (decimal). Data General have extended the format by using the prefix // for the special element.
