There is a fundamental problem with this, in that those files can and often
do contain implementation-dependent information. For example, <stdio.h>
must contain definitions of the getc and putc macros, which are intimately
tied to the implementation details of the rest of stdio. For another
example, it's hard to imagine a portable version of <stdarg.h>, since its
whole purpose is to cover up implementation details.

This is precisely what documentation, including standards, is supposed to
tell you. (Admittedly, it doesn't always do this very well.)
