I don't get it, std::vector::resize(n, t) always exists. The
enumeration of compiler versions is needed because: 1 - previous
versions of GCC properly declared resize(size_t, const T&), 2 - to be
as close as possible to the original implementation of the resize(n,t)
function (so we need different versions for GCC,MSVC, etc.)
