From 957381a0d26ec11a172ebfc64f892d1b31f0c193 Mon Sep 17 00:00:00 2001 From: David Kalnischkies Date: Wed, 13 Dec 2017 13:26:38 +0100 Subject: convert various c-style casts to C++-style gcc was warning about ignored type qualifiers for all of them due to the last 'const', so dropping that and converting to static_cast in the process removes the here harmless warning to avoid hidden real issues in them later on.
