If you're in the habit of writing "struct sockaddr_in sin;", you'll probably be tempted to write "struct sockaddr_un sun;". Just don't expect that code to compile on Solaris.

Is that just hardcoded into the preprocessor itself? Or is part of ANSI C. Wondering if the MS C++ compiler will do this well.

It's not and can be tuned using compiler options as mentioned in TFA. Definitely not standard.
