Hi,

this is moot argument[1]:

 [root at 9bb9a267fbb6 build]# cat /etc/redhat-release 
 CentOS Linux release 7.7.1908 (Core)

 [root at 9bb9a267fbb6 build]# gcc --version

And what is your point?  Are we supposed to handle this and possibly dozen
other corner cases in GCC 4.8 just because someone wants to use EL7 in default
setup and refuses to install and use modern toolchain? Even then, what's the
problem? You could still simply revert the commit which would make gcc6+
requirement.
