OpenSSL vs. builtin is a compile-time decision, so the builtin code
cannot be fallback at runtime.

Windows code is using either builtin code or newer OpenSSL.

You need to recompile PostgreSQL. Don't try to use non-OpenSSL
pgcrypto with OpenSSL PostgreSQL, it will crash due to symbol
conflict.

Another variant is to try to compile separate OpenSSL 0.9.8 and
compile PostgreSQL against that. So you don't need to upgrade
system OpenSSL.
