Comment 2 Brooks Davis freebsd_committer freebsd_triage 2015-02-23 19:31:05 UTC 
Is there an easy way to test this?
Comment 3 Gerald Pfeifer freebsd_committer freebsd_triage 2015-02-23 21:06:15 UTC 
I believe USE_GCC=4.9 in Makefile should allow you to simulate this.

Otherwise PR has an updated patch for "the real change".
Comment 4 Gerald Pfeifer freebsd_committer freebsd_triage 2015-02-23 21:10:21 UTC 
Make that PR 196712 in the previous comment.  Sorry.
