+memcached_server_error() can be used to look at the text of the last error
+message sent by the server to to the client.
+
+Before version 0.39 theses functions used a memcache_server_st *. In 0.39
+memcached_server_st * was aliased to memcached_server_list_st. This was
+done for a style reason/to help clean up some concepts in the code.
