Microsoft Windows QueryPerformanceCounter doesn't fail on Windows XP or later.

Posix gettimeofday called with a valid timeval address and a null second
parameter doesn't fail.

Posix clock_gettime called with a valid clock_id and a valid timespec address
is in principle allowed to fail if the number of seconds doesn't fit in time_t,
so even though no known implementation does this it is probably best to retain
the error check at this time.
