+Subject: [PATCH] Handle undef and empty LocalAddr
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+IO::Socket::INET interprets undefined and empty string LocalAddr
+arguments as an unspecified address while IO::Socket::IP returns an
+error. This seems to be one of the differences between the two
+Socket implementations. Recent IO::Socket::IP (0.39) accepts undefined
+value, but still bail outs on an empty string.
+
+To improve compatibility, this patch adds a special handling for these
+two values to be accepted as an unspecified value. Though this should
+be corrected on IO::Socket:IP side probably.
