Yeah. I'd have preferred something like that, but I'll also have to
agree with X3J11. Such is life.

My own suggestion was to make the names reserved only if the
appropriate header file was included. The fatal flaw is what happens
when you use someone else's library: you have (and should have) no
knowledge or control over what that library includes. Thus any
program that uses anything other than the Standard C library (which
is likely to be most of them) is going to have to assume that all the
names are reserved anyway. Thus this suggestion would add little or no
utility while inconveniencing the implementer a whole lot.
