Norbert Bérci questions

• How to (cross-)compile to both ARM hard- and soft-float (softfp) with a single GCC (cross-)compiler?
• What is the standard conforming way to decide what will be returned by what() from a class inherited from std::system_error without duplicating data?
• Are the copy constructor and copy assignment of std::runtime_error noexcept?
• Is there a safe way to call wait() on std::future?
