	 *	1. If the skip stack is NULL, we are outside of all #if blocks
	 *         and we are not skipping.
	 *
	 *	2. If the skip stack is non-NULL, the type of the top node in

	 *	   tokens, (such as between #if 1 and #endif, or after the
	 *	   #else of an #if 0, etc.).
	 *
	 *	3. The lexing_directive bit overrides the skip stack. This bit
	 *	   is set when we are actively lexing the expression for a
	 *	   pre-processor condition, (such as #if, #elif, or #else). In
	 *	   this case, even if otherwise skipping, we need to emit the
	 *	   tokens for this condition so that the parser can evaluate
	 *	   the expression. (For, #else, there's no expression, but we
	 *	   emit tokens so the parser can generate a nice error message
	 *	   if there are any tokens here).
