If Squid v4 built with GCC v4 leaks memory, then the leak should be
reported and Squid should be fixed. However, a leak in itself is
unlikely to be a sufficient criteria for "not capable of building"

More importantly, given the lack of Project resources, we should
continue using two versions (stable + development). While nobody has the
energy or desire to fight your version increments and branch renaming, I
doubt many have 20+% spare time to start working on three increasingly
different branches/environments: "stable" v3, "current" v4, and "Amos
special" v5. You should not introduce significant barriers between v4
and v5 until v4 truly replaces v3 as the go-to stable branch. At the
very least, you should not introduce them without a discussion/consensus!

When v4 is stable and v3 is obsolete, let's discuss whether it is time
to require GCC v5 (and latest build environments) for master. Until
then, let's conserve resources for more important matters.
