  When used in

	for (something)
	   A_MACRO;

Michael, the macro expansion would give you:

	for (something)
	{
		stmt1;
		stmt2;
	};

[Indentation is mine for clarity].  The presence of an empty statement after
the closing brace should not cause any problems, though I seem to recall
certain C compilers don't like it being placed here.
