You might not have explicitly stated that, but you have made that 
argument in this thread.

You have asserted that the compiler's behavior, and not its 
documentation, determines what should be consider a language extension.

That assertion when taken to its natural conclusion show support for the 
idea that "accidental GNU CC behavior" should be considered a language 
extension, and by becoming a language extension it would be part of GNU C.

If the behavior, and not the documentation, determines what is and is 
not an extension unless it's "accidental behavior", then how is anyone 
to know what is or is not a GNU C extension?
