I don't see anything wrong in the code (`(%esi,%eax)' is indeed not a valid
16 bit base/index, but it AFAICT it isn't meant to be).
However, your binutils are a bit old. Perhaps this is a bug they fixed ?
Anyway, maybe this solves the problem for you:
+ .code32
leal 0x200 + data_start - data_next(%ebx,%eax), %eax
+ .code16
(please report if it does)
