--- Comment #8 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch>

also in cp2k we use separate calls for getting the count_rate, count_max and
count.
I think as long as they are the same kind there should be no problem. *8
arguments resolve to the _8 version and *4 to the _4 version. Both versions
ideally have different resolution.
I would argue that allowing a single call to system_clock to have integer
arguments of different kind is somewhat of a bug in the standard, possibly
worthy of a compiler warning. In that case, I would resolve return -HUGE,0,0
i.e. system_clock of this version not supported (also allowed by the standard).
Actually, the latter seems like a good idea for integer*1 and integer*2
system_clock calls as well, since the current version is non-conforming.
> cat test.f90
INTEGER*1 :: count,count_max,count_rate
DO
CALL SYSTEM_CLOCK(count,count_max,count_rate)
write(6,*) count,count_max,count_rate
ENDDO
