where defined(__i386) is being defined??

I often saw this in some config header file. But wonder where and how __i386 is being defined. I made a grep in the project folder, but nothing shown to be doing some thing like #define __i386. Where is it being defined? I thought that variable with __ is always system variable, but which system file actually define this?

#if defined(__i386)

I believe, but I'm not completely sure, that the __i386 is defined by the compiler when you build on an architecture that is compatible with i386.
