Quite a lot.  The hardest part (last time I looked) was the exception
handling mechanism.  Interpreted builds would handle exceptions using
setjmp/longjmp calls, whereas JIT builds would use a completely
different mechanism.  There are other issues, such as the way the
dispatch table is constructed.  It would be very hard to have a single
build supporting both engines, but it might be possible to do.
