The latest patch has the disadvantage that it'll often change the behaviour of jumpahead for people on 32-bit platforms, which may lead to unnecessary breakage.

Here's a better version that only fixes mt[0] in the unlikely (but possible) event that mt[1] through mt[623] are all zero.  That should mean that users on 32-bit machines who are depending on jumpahead being reproducible won't notice (unless they're very unlucky indeed).
