C++11 std::threads vs posix threads
... compilers on UNIXes (Sun Studio on Solaris, HP aCC on HP-UX, IBM vacpp on AIX). Therefore, if your target platform is Linux only - c++11 std::thread is fine; if you also need Windows or other UNIX - boost::thread is the way to go.

As you can see, it's much more complicated than the original and necessarily so: at least one function must exist to be called recursively unless you want the code to become very complex (e.g. mana...
Difference between CC, gcc and g++?
.... You have to use alternative compiler names ('acc' IIRC). Similarly, on AIX, the system C compiler goes by names such as 'xlc' or 'xlc32'.
Classically, the default system compiler was called 'cc' and self-configuring software falls back on that name when it doesn't know what else to use.
