+Subject: [PATCH] Fix mismatched usage length, build fail on g++
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The length of const option::Descriptor usage[] is intended to be
+inferred based on the initialisation in Source/main.cpp, however, the
+extern declaration in Source/Game.hpp hard-codes it to 13.
+
+Remove the hard-coded 13 in the extern declaration, in favour of the
+inferred length.
+
+This also fixes the follwoing build failure with g++ (Debian 4.9.2-10)
