Re: [x86 setup 13/33] Header file to produce 16-bit code with gcc
From: Segher Boessenkool

gcc for i386 can be used with the assembly prefix ".code16gcc" to
generate
16-bit (real-mode) code. This header file provides the assembly
prefix.
This only works correctly with newer GCCs if you pass the
-fno-toplevel-reorder option (and it only works on older
GCC versions by accident). This option however disables
certain optimisations; but perhaps that doesn't matter all
that much here.
