The '4' to me just looks too arbitrary --- the EXE reference makes it
clear to me what it. I don't like arbitrary constants in the code and
especially not repeated several places.
As I just posted I would like us to create a global define that is
sizeof()-1 so it would be clear, perhaps CC_STRLEN() as a define name.
