38/* A program which, when compiled to assembly, exposes various guest
39   state offsets.  The program isn't executed, since that breaks
40   cross-compilation.
41
42   It does rely on the assumption that 'my_offsetof(Ty,Field)' is
43   folded to a constant at a compile time, which seems a bit dodgy
44   to me.  On gcc4 it is possible to use __builtin_offsetof, which
45   sounds safer, but that doesn't exist on older gccs.  Oh Well.
