--- Comment #1 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
If I replace everywhere int64 with int_64, the test compiles with -m64 and the
failing tests are

  t3();
  t4();
  t5();
  t6();
  t9();
  t10();
  t11();
  t12();
  t16();

only with -m64, and

  t17();
  t18();
  t19();

for both -m32 and -m64.
