I am trying to write a macro which generates more than one line of
output. Defining a macro such as

	#define foo(a,b) body \
	 more body \
	 still more

and invoking it with

	foo (one, two)

produces:

	 body more body still more

as output from the C preprocessor. I would very much like to get

	body
	more body
	still more

somehow. Is this possible? 

I know that it shouldn't matter, but in this case, it does.

I would appreciate anyone's help with this.  Thanks.
