A bit more info here; I'll try to remember to update the compile pages to
link to what the different builds are.

The most important thing is to report as bugs things that don't work in the
recompiler but do in the interpreter, it's not that the recompiler *can't*
be as accurate, it's just that it isn't. Unreported bugs are much less
likely to get fixed.
