The indent of the rephrasing is that:
- If you have a single constant, use const, e.g. (visible in debugger)
const unsigned max_stuff = 42;
- If you have multiple constants, prefer enums over #define, as
already suggested later in the guide:
enum {
A = 0,
B = 42,
C = -1
}

Defining Constant values
------------------------
-Use defines for constant values for improving readability and ease of changes.
Alternatively, use global `const` variables.

+Alternatively, use global `const` variables for individual values.
+If multiple related constants are to be defined, consider the use of
enumerations with initializers.
