You are considering only C++.  A change to the preprocessor has to
consider C also; C89 and C99 both have similar wording (C99 7.1.2p3:

	 If a file with the same name as one of the above < and >

but rather different lists of privileged headers.  I don't have copies
of POSIX or SUS to hand, but I would not be surprised to find
analogous lists and specifications there too.
