__extension__ typedef unsigned long long uint64_t;

typedef int32_t intptr_t;


typedef int8_t int_least8_t;
typedef int16_t int_least16_t;
typedef int32_t int_least32_t;


The problem stems from:

#ifndef GCC_GENERATED_STDINT_H
#define GCC_GENERATED_STDINT_H 1

#include <sys/types.h>
#include <stddef.h>
/* glibc uses these symbols as guards to prevent redefinitions.  */
#ifndef __int8_t_defined
#define _INT8_T
#define _INT16_T
#define _INT32_T
#endif
#ifndef __uint32_t_defined
#define _UINT32_T
#endif

Nice self-cancellation. :-)
