Comment (by Michel Morin <mimomorin@…>):

 Sorry, Eric. Could you revert the previous patch?
 I found a regression caused by the patch (which was not caught by the
 test).

 I've realized that gcc-4.4 is really a mess to implement "const reference
 binding of rvalue ranges".
 We shouldn't try to implement it unless we have reliable test.
 Bugs in gcc-4.4 are appeared when using BOOST_FOREACH in function
 templates.
 We should extend the existing test to cover those cases.

 So it seems that we have only two options for this release: A or B of
 comment 23.
