             Bug #: 54040
           Summary: [x32] Incorrect timeval and timespec
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ada
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: hjl.tools@gmail.com


X32 has

/* A time value that is accurate to the nearest
   microsecond but also has a range of years.  */
struct timeval
  {
    __time_t tv_sec;            /* Seconds.  */
    __suseconds_t tv_usec;      /* Microseconds.  */
  };  

and

struct timespec
  {
    __time_t tv_sec;            /* Seconds.  */
    __syscall_slong_t tv_nsec;  /* Nanoseconds.  */
  };

__time_t, __suseconds_t and __syscall_slong_t are 64-bit integers
in x32. But ada run-time assumes all of them are long, which is
32-bit for x32.
