I think the later scanning can be done when generating the DWARF debug symbols
(cf. PR37132) in trans-decl.c. While not very important, I find such a warning
useful. (One needs to be careful about those declared in a module or accessed
via host association. Fortunately, namelists may not be declared in a BLOCK.)
