Beta 18 breaks gettimeofday

According to the SunOS 5.5 man page:

NAME
     gettimeofday, settimeofday - get or set the date and time
...
RETURN VALUES
     A -1 return value indicates that an error occurred and errno
     has been set.

Ultrix (4.3) and IRIX (5.3) man pages state that -1 indicates error and 0
indicates success.

The portable thing to do seems to be checking the return value against -1.
This will work with the cygnus implementation.

  if (gettimeofday(tvp, NULL) == -1) {
     printf("failed\n error was : %s\n", strerror(errno));
  } ...
