Values aside from EXIT_SUCCESS and EXIT_FAILURE are tricky.
ttn 2004-05-12
Values aside from EXIT_SUCCESS and EXIT_FAILURE can be used to indicate
finer gradations of failure. If this is the only information available
to the caller, clamping such values to EXIT_FAILURE loses information.
If there are other ways to indicate the problem to the caller (such as
a message to stderr) it may be ok to clamp. In all cases, it is the
relationship between the program and its caller that must be examined.
