As a compiler implementer, I must object. The universal convention is that symbols starting with a double-underscore are for the implementation's use, not for use by end-user software. Please stop reading the headers and trying to figure out how the implementation-specific macros work. Stay with the documented macros. If you are concerned about compiler or runtime bugs, write a configure test for them, like any other feature. Don't put these hacks into the source code.
