Recursive Definitions: Trouble or Bad news?

[Dr. T. Andrews]

I should be interested to know the latest ANSI wisdom on a construct
requesting that token BLUNGE be replaced by itself:
	#define BLUNGE BLUNGE

Intended use is to "remember" that we have done a "typedef" by
defining a preprocessor symbol which has the same name as the type.
