From the article: " GCC can't be used because the GCC version of std::thread has copyleft licensing provisions in it" This is not a claim I had previously heard before. There are a couple other head-scratchers in there: "never heard of lvalue/rvalue distinctions as defined by the C++ 11 language designers? Then don't try to use C++ 11!" This seems a little odd because lvalue/rvalues have been part of c++ since day one (in fairness, c++11 does add rvalue references, but still) I had not previously heard of DMC, and based on this blog post I'm not really that impressed.
