If one of those compilers have issues with std::lround (which i seriously doubt) then we should perhaps look into replacing it with qRound. However, Qt is also moving away from it's own algorithms in favor of the stl ones so we should stick to the std:: versions.

I'm torn on this one.

This is a minor edit (mainly thinking about the potential qRound version) that would fix the current master to work with an old platform. Without having any downsides (apart from possible future depreciacion of qRound).

But, on the other hand, something else will probably be brought in soon that will require some more essential c++11 things, and break on osx 10.7. So, one wonders whether a patch that just prolongs the inevitable has a purpose. :)
