_int64 no nombra un tipo
En mi pch file Tengo las siguientes definiciones:
#if (_MSC_VER < 1300)
typedef signed char int8_t;
typedef signed short int16_t;
typedef signed int int32_t;
typedef unsigned char uint8_t;
typedef unsigned short uint16_t;
typedef unsigned int uint32_t;
#else
typedef signed __int8 int8_t;
typedef signed __int16 int16_t;
typedef signed __int32 int32_t;
typedef unsigned __int8 uint8_t;
typedef unsigned __int16 uint16_t;
typedef unsigned __int32 uint32_t;
#endif
typedef signed __int64 int64_t;
typedef unsigned __int64 uint64_t;
Cuando construyo mi aplicación, aparece un error en
typedef signed __int64 int64_t;
typedef unsigned __int64 uint64_t;
que dice que _int64 no nombra un tipo. ¿Cuál podría ser el problema
