Right, but the patches will be attached here for anybody who needs them.

Closing as WONTFIX then.

Backport of patches but for gcc 6.5

Just for the reference, I backported the fix also to gcc 6.5
It applied almost cleanly.

Given your comment, I don't think it is worth opening a new bug just for that?
So I leave the patch here for the record.

GCC 4.8 is no longer supported or maintained, so nothing is going to be
backported to that branch here (downstream vendors might still support it and
make changes to their versions).

Those fields were set incorrectly, I've changed them now.

The gcc-6 branch is going to close in the next week or two, so I doubt this
will get backported to that branch either, unless it fixes a regression in GCC
6.4 when compared to previous releases.
