+	Version 3 -- 1987-06-16 -- D.N. Lynx Crowe

+	WARNING:  Be sure that the 'mode' in the sizeof(mode) in va_arg
+	matches the size of the actual argument on the stack.  If it doesn't,
+	improper argument list fetches will occur.
+	(Lattice has problems with this, as all arguments except double are
+	the same size.)
