From af2d22254e8ee4558d3803372735c0b4f6046cd2 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 2 Dec 2020 22:49:29 +0900 Subject: gcc-plugins: remove code for GCC versions older than 4.9 Documentation/process/changes.rst says the minimal GCC version is 4.9. Hence, BUILDING_GCC_VERSION is greater than or equal to 4009.
