nasm problem?

[[ B l u r B ]]

hi... i have an asm source 16/32bit code mix... thus im using a.out file 
format when compiled with nasm -f aout and when I going to linkit to 
another c file all the call to the c files (ex: _main) are ok but there is 
something with the offset of the data..

16bit code from the asm source loads my gdt and the dissasembling of the 
binary flat linkage show that this gdt is in 0x200... later on I add more 
instructions to the asm file and the dissasembling show the same address.

I link this unique file with

ld b.o --stats --verbose --warn-common --warn-once -o test.bin -oformat 
binary -Ttext=0

and nasm -f aout b.asm...

if you find the bug.. or let me know what im doing wrong i would appreciate 
so much... sorry for my english..

thanks in advance.
