The compiler 1.076 is calling the DFL Control file. These are all 
the lines where DEFAULT_SCALE) is found:

		return calcScale(area, toScale, DEFAULT_SCALE);
	const Size DEFAULT_SCALE = { 5, 13 };
	Size autossz = DEFAULT_SCALE;

Tehse are all the lines where Size is found in all the dfl 
library files:

I just don't know what the error means to be able to figure out 
what the problem is.  Thanks for the help.
