From d6d3db05436952f68f47d35df58ad5050b1f2d66 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Sat, 31 Mar 2018 21:28:32 +0200 Subject: [PATCH] build: Improve GCC version detection This now makes sure that the beginning of the version number gets checked and "4.4.5" will not match was a supported version. GCC 8 and GCC 9 are now marked as supported, but we probably have to fix some problems for them.
