Yes. it seems to work. May I push that change? In terms of AMD64
and JIT. The bundled version of GNU lightning doesn't compile for
AMD64 and after using the latest 1.x version it compiles but fails
quite quickly.

 current = (method_entry *) xmalloc (MAX_BYTES_PER_BYTECODE * (size + 2));

is not enough for inlined primitives on AMD64. But even then I had
crashes on the travis-ci system. Do you remember if xlat.c ever
worked on AMD64?
