Coq 8.4pl6 has been released. SRC_URI: https://coq.inria.fr/distrib/V8.4pl6/files/coq-8.4pl6.tar.gz I've confirmed that a copy of coq-8.4_p5.ebuild named coq-8.4_p6.ebuild worked well, with replacing "${FILESDIR}/${P}" with "${FILESDIR}/${PN}-8.4_p5". After installation, I compiled Ssreflect and MathComp and proved "HilbertS" in "An Ssreflect Tutorial", section 2.1. It succeeded. Reproducible: Always
