Thanks,
Harald

Fortran: do not restrict PDT KIND and LEN type parameters to default integer
gcc/fortran/ChangeLog:
PR fortran/102917
* decl.c (match_attr_spec): Remove invalid integer kind checks on
KIND and LEN attributes of PDTs.
gcc/testsuite/ChangeLog:
PR fortran/102917
* gfortran.dg/pdt_4.f03: Adjust testcase.
