With in-line assemly in djgpp can you assume that es==ds when
it gets enters your inline assemly ? 

Also does the es register have to be preserved (if you change es do you
have to set it back its its original value) ?

Also if you have to preserve the es register does it have to be done
manually ("pushl %%es\n" and "popl %%es\n") or can you put something in
the 'registers clobbered' section ("ecx" works but "es" does not)?

Thanks.
Jens.
