* Revert the fix PR c/33763, and just disable the sorry message,
  taken from the branch. Closes: #678589. LP: #1062343.
* Update libgo to 1.0.3.
* Go fixes:
  - Fix a, b, c := b, a, 1 when a and b already exist.
  - Fix some type reflection strings.
  - Fix parse of (<- chan <- chan <- int)(x).
  - Fix handling of omitted expression in switch.
  - Better error for switch on non-comparable type.
* Fix PR debug/53135 (ice on valid), PR target/54703 (x86, wrong code),
  PR c++/54777 (c++11, rejects valid), taken from the 4.7 branch.
* gcc-4.7-base: ensure smooth upgrades from squeeze by adding
    Breaks: gcj-4.4-base (<< 4.4.6-9~), gnat-4.4-base (<< 4.4.6-3~)
  as in gcc-4.4-base (multiarch patches re-worked in 4.6.1-8/4.4.6-9).
  Fixes some squeeze->wheezy upgrade paths where apt chooses to hold back
  gcc-4.4-base and keep gcj-4.4-base installed instead of upgrading
  gcc-4.4-base and removing the obsolete gcj-4.4-base (Andreas Beckmann).
  Closes: #677582.
* Add arm64 support, partly based on Wookey's patches (only applied for
  arm64). Disabled for arm64 are ssp, gomp, mudflap, boehm-gc, Ada, ObjC,
  Obj-C++ and Java).
