Note the documented requirement for bootstrapping is a "ISO C++11 compiler". We fail to specifically say which GCC version fulfills this, the GCC 4.8 requirement for non-bootstrap is technically unrelated but it will run into the same issues I think. Generally when we refer to a major GCC version picking the latest bugfix release is always recommended. I'm posting a proposal to amend the documentation.=
