Gah, autocomplete bug strikes again.

Right. Full compatibility with OpenSSL 3.0 took a large amount of effort that I'm not willing to backport. You'll have to upgrade if you want to use OpenSSL 3.0.

To my knowlege, OpenSSL 3 is only supported as of PHP 8.1.0;
sticking with OpenSSL 1.1.1 for older PHP branches should be fine.

Description:
------------
Many errors related to openssl 3.0.0 begin appearing midway through the PHP build. The build failed.

A build with openssl 1.1.1l completes successfully.

Below, I have listed the first errors / warnings that appeared below.

Generally, php.net recommends we upgrade to the latest openssl and I would thus like to know whether openssl 3.0.0 (the latest version) is currently supported by PHP or whether we should stick with 1.1.1l

thanks
