Hi,

as almost expected r233572 needs to be back-ported to gcc-5 and gcc-4.9
branches in order to be built by gcc-6.  It applies cleanly to both
branches.  But unfortunately PR 69881 prevents boot-strapping gcc-4.9
in the moment.

Boot-strap and regression-test of gcc-5 on x86_64-pc-linux-gnu.
OK for gcc-5 and gcc-4.9 when PR 69881 is resolved?


Thanks
Bernd.
