Author: imp Date: Thu Aug 8 20:09:36 2019 New Revision: 350778 URL: https://svnweb.freebsd.org/changeset/base/350778 Log: Stopgap fix for gcc platforms. Our in-tree gcc doesn't have a no-tree-vectorize optimization knob, so we get a warning that it's unused. This causes the build to fail on all our gcc platforms. Add a quick version check as a stop-gap measure to get CI building again.
