Right. I agree.
One should have the definition only in the .h file. Eg:
extern value_string some_value_string_array[];
And then, in the primary place it is used:
#include "the_include_file_with_the_val_strings.h"
...
value_string some_value_string_array[] = {
{SOME_VAL, "The string for SOME_VAL"},
{0, NULL}
}
