polymake does not build with gcc.7.1

[videlec]

The polymake experimental package does not compile with gcc (GCC) 7.1.1 (see attachment: polymake-3.1.log). In this thread on polymake forum upstream reports the same issue. We adapt a very simple patch proposed in the thread.

Upstream: Reported upstream. Developers acknowledge bug.
