i've got an older project where features where integrated based on an
6.3.0 branch

no bug fixes - only new features and no backporting was done :(


i now want to reintegrate these new features back into mainline (not
directly into head due to amount conflicts)

but somewhere around "GCC 7 Stage 4 (starts 2017-01-20)" could work i think

or should i try to directly merge with a 7.1 tag branch, i've no idea
how many changes where done
