It will be the sum of the sizes of _some_ of the sections in
the a.out file plus the size of any holes between sections.

The size of the binary file will be one larger than the
difference between the lowest addressed byte and the highest
addressed byte in the set of sections whose "L" flags are set.

The easiest way to find out the size of a binary file is to
generate one and do "ls -l".  :)

Yes, there's a relationship, but it's non-obvious.

Debug info does not contribute the the size of a binary file.
