-------------------------------------+--------------------------------------
 gcc-4.6.0 made Boost.foreach unusable in 1.46.1 because the rvalue
 detection
 no longer works. Now, there is a fix in trunk for it but it has a nasty
 side
 effect, namely a warning that is emitted whenever foreach is used with an
 rvalue and -Wconversion is turned on. Sadly, this warning cannot be
 ignored
 by including Boost with -isystem because the code is generated by a macro,
 obviously.

 I would be glad if this could be fixed somehow because -Wconversion is a
 crucial warning option to me.
