+Subject: libxtables: compiler warning fixes for NO_SHARED_LIBS
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Fixes two issues with NO_SHARED_LIBS:
+ - #include <dlfcn.h> is ifdef'ed out and thus dlclose()
+ triggers an undeclared function compiler warning
+ - dlreg_add() is unused and thus triggers an unused
+ function warning
+
+Test: builds without warnings
