Ok. I attach some test codes to confirm section alignment.

And I tested them like this.

nasm -f aout seg-a1.asm
nasm -f aout seg-a2.asm
nasm -f aout seg-a3.asm
gcc seg.c seg-a1.o seg-a2.o seg-a3.o

The result from seg.exe is the following.

-----
test1_data = 0x20050
test2_data = 0x20060
test3_data = 0x20070
test1_bss = 0x20100
test2_bss = 0x20110
test3_bss = 0x20120
test1_text = 0x101a8
test2_text = 0x101ac
test3_text = 0x101b0
-----

I think this means .data and .bss are 16-bytes aligned, and .text is 
4-bytes aligned, so kludge for aout is acceptable.

What do you think about this ?

No problem.
