In r207132, I have now committed a merge of trunk r206958 (2014-01-23).
Compared to a pristine trunk r206958 build, there is one regression:

    FAIL: g++.dg/gomp/declare-simd-1.C -std=c++98 (internal compiler error)
    FAIL: g++.dg/gomp/declare-simd-1.C -std=c++11 (internal compiler error)

In my understanding, the only gomp-4_0-branch-specific change that is a
candidate to cause this is r205214 (Ilya Tocar, commited by Kirill
Yukhin) for "LTO" streaming.  As I couldn't easily tell what's wrong (all
changes from r205214 are still present; there were no obvious conflicts),
could you guys please have a look at that one?

The good news is that the merge in fact doesn't cause any conflicts (that
is, when applying that patch series on top of the new r207132) -- but I
have not built and tested it.
