K&R (original) 4.3 (page 71, paragraph 4):
	"It is generally safe to deal with a variable number of arguments 
	if the called function doesn't use an argument which was not actually
	supplied, and if the types are consistent".

I take that as a constraint when writing a C compiler.  Often there are more
efficient ways of passing parameters (such as callee cleans up stack), but
that is not "the C way".
