The following is legal C code:
	char *x="\
	#endif" /*
	#ifdef foo */
It has always been legal to enclose such code in an #if/#endif.  Your
suggestion would break this.

If you want to prevent sections of code from being compiled, use #if/#endif.
If you want to include descriptive text, use a comment.

Btw, you said `#ifdef 0'; this should be `#if 0' (or that godawful pdp11ism
`#ifdef notdef')
