+Subject: [PATCH] Fix an ODR violation
+
+Building with CFLAGS="-flto -Werror=odr -Werror=lto-type-mismatch
+-Werror=strict-aliasing" CXXFLAGS="-flto -Werror=odr
+-Werror=lto-type-mismatch -Werror=strict-aliasing" LDFLAGS=-flto fails
+due to a violation of the one definition rule. There are two different
+definitions of TOption that are both linked into the znc binary.
+
+Fix this by putting them into anonymous namespaces.
+
