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. :-)
