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