PR fortran/63570
* check.c (gfc_check_random_init): New function. Check arguments of
RANDOM_INIT.
* gfortran.h (GFC_ISYM_RANDOM_INIT): New enum token.
* intrinsic.c (add_subroutines): Add RANDOM_INIT to list of
subroutines.
(gfc_check_intrinsic_standard): Introduce Fortran 2018 check.
* intrinsic.h: Add prototypes for gfc_check_random_init and
gfc_resolve_random_init
* intrinsic.texi: Document new intrinsic subprogram.
* iresolve.c (gfc_resolve_random_init): Resolve routine name.
