Just tried to build the released 4.8.3 and still see the original problem (see
error messages below).  Same is true at the tip of the gcc-4_8-branch in svn
(at r216525).

However, 4.9.1 is fine.

So, please don't close if 4.8.x is still open to bug fixes.
If 4.8. is closed, then this bug can be closed too.
