your patch looks fine. Unfortunately I've overseen your mail in the daily
flood and made some changes to openssl too. Why didn't you update the wiki
page by going on? It's exactly for the purpose of knowing what's currently
going on :) In any case, could you please merge with the current state and
do a PR? I'll merge it then.

One thing though about openssl and issues you mention in the gist - the
'int' vs. php_int_t overflows on 64 bit should be fixed on run time
checking against INT_MAX. Maybe that's what you could extend for the
openssl ext. That's an issue in many other libs too.

Thanks for you work

Anatol
