I didn't say it was right, I said that where it came from.  In any case
I'd be willing bet

#define NUM_OBJ 100 

is much more prevalent than

enum {
 num_obj = 100
};

even in C code written in the last five years.  Idioms are hard to
kill. (I'll admit that I'm among them - type safety concerns means I
tend to set compiler switches so that I get warned about int-to-enum
comparisons and enum-to-other-enum comparisons, so this technique
doesn't even *work* for me)

Either way, the convention did not cross from Java to C++, it went
entered C++ and Java from the common ancestor, C.
