 *

 * parser is currently skipping tokens, (such as within #if
 * 0...#else).
 *
 * The RETURN_TOKEN_NEVER_SKIP macro is a lower-level variant that
 * makes the token returning unconditional. This is needed for things
 * like #if and the tokens of its condition, (since these must be
 * evaluated by the parser even when otherwise skipping).
 *
 * Finally, RETURN_STRING_TOKEN is a simple convenience wrapper on top
 * of RETURN_TOKEN that performs a string copy of yytext before the
 * return.

	 * The parser maintains a skip_stack indicating whether we should be
         * skipping, (and nested levels of #if/#ifdef/#ifndef/#endif) will
         * push and pop items from the stack.
	 *
	 * Here are the rules for determining whether we are skipping:
	 *
	 *	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
	 *	   the stack determines whether to skip. A type of
	 *	   SKIP_NO_SKIP is used for blocks wheere we are emitting
	 *	   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).
