Detailed Description

********************* AOUT "OPTIONAL HEADER" *********************

Linux COFF must have this "optional" header. Standard COFF has no entry location for the "entry" point. They normally would start with the first location of the .text section. This is not a good idea for linux. So, the use of this "optional" header is not optional. It is required.

Do not be tempted to assume that the size of the optional header is a constant and simply index the next byte by the size of this structure. Use the 'f_opthdr' field in the main coff header for the size of the structure actually written to the file!!
