It's certainly come up before. See e.g.
<https://sourceware.org/ml/libc-alpha/2014-04/msg00522.html> regarding
__int128. If 4.6 had already been required then, no-one would have needed
to point out the lack of __int128 support before 4.6, or discuss how to
test for it or work around its absence (presuming the use was only for
64-bit systems). (And, yes, I consider __int128 a longstanding feature.)
