I need to install gcc 4.9 on CentOS 6. And I usually do the following:

yum install -y centos-release-scl
yum install -y devtoolset-3-gcc-c++ make cmake re2c libuuid-devel libxml2-devel zlib-devel

Today I found out that only devtoolset-6 and devtoolset-7 are available now, all other version are removed.

Any ideas? I can't use gcc >= 5.
