Concise and good explanation. :)

So the syscalls of a Linux/Unix machine are the same, b/c of the POSIX API. The POSIX API is a standard for *nix OSes.

Now, we have compilers such as gcc, clang and Microsoft's C++ compiler. Do they decide on their own ABI (specification of how things should be implemented in the lowest levels) then?:
