+Subject: [PATCH] tcp: fix some compiler warnings with enable-tls-openssl
+
+When --enable-tls=no and --enable-tls-openssl=yes, the following
+compiler errors are reported:
+
+```
+| ../../git/src/tcp.c:3765:1: error: no previous declaration for 'relpTcpGetRtryDirection_gtls' [-Werror=missing-declarations]
+|  3765 | relpTcpGetRtryDirection_gtls(LIBRELP_ATTR_UNUSED relpTcp_t *const pThis)
+|       | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
+| ../../git/src/tcp.c:3583:1: error: 'relpTcpChkPeerName' defined but not used [-Werror=unused-function]
+|  3583 | relpTcpChkPeerName(NOTLS_UNUSED relpTcp_t *const pThis, NOTLS_UNUSED void* cert)
+|       | ^~~~~~~~~~~~~~~~~~
+```
+
+Fix these by:
+    1. Add static on the openssl path for relpTcpGetRtryDirection_gtls.
+    2. Move the relpTcpChkPeerName forward declaration to another ifdef
+       leg.
+    3. Wrap relpTcpChkPeerName in gnutls-based ifdef.
+    4. Remove relpTcpChkPeerName_gtls from openssl path.
+
+Upstream-Status: Backport [https://github.com/rsyslog/librelp/pull/255]
