Does Lattice C 4.0 fix the $#@(%&^*&^ misfeature common to all
other Lattices (both MS-DOG and Amiga) whereby the use of a macro
may NOT be split over two source lines (even escaping the newline)?

e.g.

#define	MAX(a,b)	(((a)>(b))?(a):(b))

main()
{
   ...
   foo = MAX(		Extremely_Long_And_Complicated_Expression_Number_1,
			Another_Extremely_Long_And_Complicated_Expression );
}

lc1 of something like the above would produce the message 'Invalid macro usage'.
***EVERY*** other C compiler preprocessor I've used accepts macros split
across lines.  ***WHY*** doesn't Lattice?  (P.S. no flames about this particular
example; it was just an easy one to think of off the top of my head).
