I would like to nominate this patch for gcc-5.2 release. According to
downstream bugreport [1], gcc-5.1 is unusable for 64-bit wine:

"Breaks all of wine, no easy workaround -> blocker."

Due to severity of this bug, and importance of Wine, I'd like to
postpone the 5.2 release for a week, so this bug gets some testing in
the mainline, before it is backported to gcc-5 branch

Uros.
