HandlerSocket is a NoSQL plugin for MySQL, working as a daemon inside the mysqld process, to accept tcp connections, and execute requests from clients. HandlerSocket does not support SQL queries; instead it supports simple CRUD operations on tables.
The warnings in the category 'extra-portability' are now enabled by '-Wall'.
In previous versions, one has to use '-Wextra-portability' to enable them.
So handlersocket cannot be built and fails with this error
Running automake ...
