Description of problem: gcc -Wall generates a warning "null argument
where non-null required" when the second argument of utime() is NULL.
A null second argument is legal per the man page, per the Single Unix
Spec, and per experiment, so the warning is bogus.  Accordingly, the
THROW spec in /usr/include/utime.h is wrong.

Version-Release number of selected component (if applicable):
glibc-headers-2.3.3-55

How reproducible: Always.

Steps to Reproduce:
[tgl@rh1 ~]$ cat utimetest.c
#include <stdlib.h>
#include <sys/types.h>
#include <utime.h>

int main(int argc, char** argv)
{
  char * path = argv[1];

  utime(path, NULL);

  return 0;
}
[tgl@rh1 ~]$ gcc -Wall utimetest.c
utimetest.c: In function `main':
utimetest.c:9: warning: null argument where non-null required (arg 2)
[tgl@rh1 ~]$ ./a.out a.out
[tgl@rh1 ~]$ -- note lack of crash
 
Actual results:


Expected results: No warning.
