The thread contains some more test cases. All of them should be checked.

The program in comment 0 looks wrong to me:
   use n
   use n, only: b=>a
does not import "a" per paragraph 7 of Fortran 2008's "11.2.2
The USE statement and use association".

Thus, gfortran rightly complains about:
   public a, b
           1
Error: Symbol 'a' at (1) has no IMPLICIT type


In the thread, the example "bug1b.f90" (date: Jan 5, 7:36 am) is the same as PR
51578. All other examples are - valid or invalid - correctly handled by
gfortran.

Thus, I mark this PR as duplicate of PR 51578.
