Paul J. Lucas has proposed merging lp:~paul-lucas/zorba/bug-886543 into 
lp:zorba.

Requested reviews:
  Paul J. Lucas (paul-lucas)
  Matthias Brantner (matthias-brantner)
Related bugs:
  Bug #886543 in Zorba: "Fake std::move() doesn't always work under g++ 4.6.x"
  https://bugs.launchpad.net/zorba/+bug/886543

For more details, see:

Added hack fix is to make it move(T const&) and insert a const_cast. This is 
ugly because it shouldn't move a const T, but since this is a fake move() 
anyway, it probably doesn't matter.
