Log message:
	Support NULL type.
	It occurs in approx one place:
	elego/graphicutils/src/RsrcFilter.m3
	In the generate C, it called "M3_NULL_T".
	
	work in progress, not to be completed particularly soon:
	The goal here is to make the C backend independent of the
	flag in m3front that guides the order of nested function output.
	
	Part of the strategy is to give M3CG.Replay a range to replay.
	i.e. from begin_procedure to end_procedure.
	
	Instead, for now, the C backend has a requirement on the m3front flags.
	That is ok. The NT/x86 backend has a similar requirement.
