Well, it wouldn't be free. The problem is:
typedef struct nameData
{
char data[NAMEDATALEN];
} NameData;
If it were not a compile-time constant, every bit of code that uses
NameData (or otherwise depends on NAMEDATALEN being constant) would
have to be changed. That would be invasive and likely have at least a
minor performance cost.
