- * Suppress OpenSSL 3.0 deprecation warnings for DH API.

+ * Suppress OpenSSL 3.0 deprecation warnings for the DH API: it is deprecated
+ * but still functional, and still required for protocol compatibility. The
+ * project sets this for every target (see the top level CMakeLists.txt); it
+ * is repeated here because it only takes effect if it is defined before the
+ * first OpenSSL header is pulled in.
