Right, and that is just a variant of RHEL6, whose native compiler is indeed
gcc 4.4.x.
The various DTS are still availabe to get access to more modern compilers,
see
http://linux.web.cern.ch/linux/devtoolset/
DTS 2 is gcc 4.8.x and 3 is 4.9.x, 4 is 5.2.x. All can be installed on
SLC6, and any binary compiled with those tools will run on
RHEL6/CentOS6/SLC6 without needing to install anything.
