Steve, First, it is needed to remove the line
mpz_t put_size, get_size; in gcc/fortran/check.c, otherwise compiling the file with -Werror (default) fails. Second, the patch breaks the interface of RANDOM_SEED(GET/PUT...) as shown for gfortran.dg/random_seed_1.f90 and the original test in pr52879. This likely makes the patch stage 1 material. AFAIU my tests in pr52879, comment 1, the generated sequence for real does not depend on the four first integers. From a user point of view, this surprising (may be undocumented, I did not check). So I think the seed generation should keep the present properties and only add a way to randomize the 12 integers. Thanks for working on it. Dominique
