+<p>
+The <tt>__main</tt> call is inserted by the C/C++ compiler in order to guarantee
+that static constructors and destructors are called when the program starts up
+and shuts down.  In C, you can create static constructors and destructors by
+using GCC extensions, and in C++ you can do so by creating a global variable
+whose class has a ctor or dtor.

+<tt>llvm/runtime/GCCLibraries/crtend/</tt> directory in the source-base, and is
+linked in automatically when you link the program.
