This is the actual bug, and it might be an autoconf issue ...

... as in resuse.h, we have 

#if HAVE_SYS_RUSAGE_H
/* This rusage structure measures nanoseconds instead of microseconds.  */
# define TV_MSEC tv_nsec / 1000000
# include <sys/rusage.h>
#else
# define TV_MSEC tv_usec / 1000
# if HAVE_WAIT3
#  include <sys/resource.h>
# else
/* Process resource usage structure.  */
struct rusage
{
  struct timeval ru_utime;      /* User time used.  */
  struct timeval ru_stime;      /* System time used.  */
  int ru_maxrss, ru_ixrss, ru_idrss, ru_isrss,
  ru_minflt, ru_majflt, ru_nswap, ru_inblock,
  ru_oublock, ru_msgsnd, ru_msgrcv, ru_nsignals,
  ru_nvcsw, ru_nivcsw;
};
# endif
#endif

so that the redefinition is only use when HAVE_WAIT3 fails.  Now, we don't
need the redifinition, but autoconf doesn't tell us.

Any debian-alpha people here who could comment on this?  Should we add an
additional  "or if ALPHA_LINUX"  on Alpha?
