+ * gfortran.h: Declare gfc_do_concurrent_flag as extern.
+ * resolve.c: Rename do_concurrent_flag to gfc_do_concurrent_flag
+ and make non-static.
+ (resolve_function): Use gfc_do_concurrent_flag instead of
+ do_concurrent_flag.
+ (pure_subroutine): Likewise.
+ (resolve_code): Likewise.
+ (resolve_types): Likewise.
+ * intrinsic.c (gfc_intrinsic_sub_interface): Raise error for
+ non-pure intrinsic subroutines within DO CONCURRENT.
