--- Comment #9 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
Note that after r11-7501 the test in comment O gives cat run time:

% gfc pr57871.f90 -freal-4-real-16
% ./a.out
 kind(1.0_p1)           4 precision(1.0_p1)           6
 kind(1.0_dp)           8 precision(1.0_dp)          15

instead of

% gfca pr57871.f90 -freal-4-real-16
% ./a.out
 kind(1.0_p1)          16 precision(1.0_p1)          33
 kind(1.0_dp)           8 precision(1.0_dp)          15
