+Subject: [PATCH] Fix error: call of overloaded distance is ambiguous
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The boost::iterators::distance function template is an adapted version
+of std::distance for the Boost iterator traversal in 2.68 it has started
+to fail with argument dependent lookup and compiler is erroring out
+
+with
+
+error: call of overloaded ‘distance'
+
+boost implementation of distance is protected against being found by ADL
+
+The way function is called in libdhcp means it will be found via ADL and
+all namespaces will be considered which is providing problematic since
+its getting it from both std:: and boost:: namespaces
+
+so let it not rely on ADL by qualifying then calls with std:: namespace
+
+Upstream-Status: Submitted [https://github.com/isc-projects/kea/pull/103]
