#define   CONC_LINE(a)  CONC(a, __LINE__)
#define   CONC(a, b)  __CONC(a, b)
#define __CONC(a, b)  a##b
// ...
int CONC_LINE(name);

Способ присовокупить к названию переменной номер строки, где её объявили.
Объясните кто-нибудь, почему #define CONC_LINE (a) __CONC ( a, __LINE__ ) дает: name__LINE__?
