+Subject: [PATCH] BUILD: fix compilation for OpenSSL-3.0.0-alpha17
+
+Some changes in the OpenSSL syntax API broke this syntax:
+  #if SSL_OP_NO_TLSv1_3
+
+OpenSSL made this change which broke our usage in commit f04bb0bce490de847ed0482b8ec9eabedd173852:
+
+-# define SSL_OP_NO_TLSv1_3                               (uint64_t)0x20000000
++#define SSL_OP_BIT(n)  ((uint64_t)1 << (uint64_t)n)
++# define SSL_OP_NO_TLSv1_3                               SSL_OP_BIT(29)
+
+Which can't be evaluated by the preprocessor anymore.
+This patch replace the test by an openssl version test.
+
+This fix part of #1276 issue.
