I gave up on llvm at develop, and tried llvm, which tried to give me 8.0.0.  It did not report gcc 4.8.5
as being too old, but it did give the same error as above.

Why does the source use (9.223372036854775807e+18 / 1.0e+9) rather than
(9.223372036854775807e+9) ?  The latter is really a constant and not an expression,
so it would not give the same error.

I am also curious as to what a constant with 19 significant figures would be used for.

Is there some compiler that would work?

	Thanks again,
