AFAIK all major Unices have migrated from older a.out to ELF:

http://www.freebsd.org/doc/handbook/binary-formats.html

By the way, binutils has lots of other useful stuff besides readelf, for
example nm and objdump.     You have hours of happy man-page reading ahead
of you!

If I didn't have a deadline, I'd make a .c file with

int a1;
int a2;
. . .
int a100;

and compare it's size to

int a[100];

but I have a deadline right now.    I don't know the answer to the earlier
question about the function declarations and memory and would like to
explore that too, but maybe I should try to get my presentation finished
before my business trip instead  .  .  .

Spend much time at the cutting edge and you're liable to get cut.
