+// For WebCore we need to avoid having static constructors.
+// Our strategy is to declare the global objects with a different type (initialized to 0)
+// and then use placement new to initialize the global objects later. This is not completely
+// portable, and it would be good to figure out a 100% clean way that still avoids code that
+// runs at init time.
+
+// Bug 1279152.  This is a hack.  For MSVC, AVOID_STATIC_CONSTRUCTORS will not
+// be set in config.h, because it's not supported.  The problem is that, we
+// need to take a bunch of the paths that !AVOID_STATIC_CONSTRUCTORS takes, so
+// unless we fork a bunch of files to fix the ifdefs, this is the easiest thing
+// to do:
+// - Leave AVOID_STATIC_CONSTRUCTORS undefined, if we define it, the variables
+//   will not be extern'd and we won't be able to link.  Also, we need the
+//   default empty constructor for QualifiedName that we only get if
+//   AVOID_STATIC_CONSTRUCTORS is undefined.
+// - Assume that all includes of this header want ALL of their static
+//   initializers ignored.  This is currently the case.  This means that if
+//   a .cc includes this header (or it somehow gets included), all static
+//   initializers after the include will be ignored.
+// - We do this with a pragma, so that all of the static initializer pointers
+//   go into our own section, and the CRT won't call them.  Eventually it would
+//   be nice if the section was discarded, because we don't want the pointers.
