openssl_missing.h seems to be the offending file, as it appears to redefine functions / macros that are already present in the OpenSSL version you use. I can only assume that openssl_missing.h defines things that are missing in older OpenSSL versions, i.e. is some sort of forward (or is that backward... I'm always confused by the meaning of the direction) compatibility layer. If that is the case, it might need a bit of editing and use OpenSSL's version macros to determine what macros / functions actually need to be defined in openssl_missing.h. The version macros are documented in doc/man3/OpenSSL_version.pod since OpenSSL 3.0.
