The reason is a change in OpenSSL: the ASN1_STRING is now opaque and can
no longer be accessed directly. Now, accessor functions must be used.
See <https://openssl-library.org/post/2026-04-13-asn1_string/>
The attached diff fixes this for me; something like this seems to be
necessary for OpenSSL >= 4.0.

Thanks. Regarding the #ifdefs, wouldn't the accessor functions also work
on older OpenSSL releases, too, so that mutt could switch to the
accessor API wholesale?
