double_buffer is far pointer(32-bit)??

x86 assembly code "les" means "load es", it does this :

Load the far pointer  segment -> es (16-bit)
                               offset     -> di  (16-bit)

But, DJGPP is 32-bit, It doesn't need segment,
and offset is 32-bit, it is default!

<Borland>

les di, double_buffer

<DJGPP>

...
movl %3, %edi
/* %3 == double_buffer, it is far pointer, %edi is 32-bit */
..."
:
: ...
: ... , "g" (double_buffer)

When I use "les" in DJGPP, I did above...
If it is wrong, tell me...
My English is short! I'm sorry!   :-)
