[Bug fortran/21257] New: Duplicate use of construct name

["kargl at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Consider the following program:

   program f
     integer i
     loop: do i = 1, 5
              print *, i
           end do loop
     loop: do i = 1, 5
              print *, i
           end do loop
   end program f

Gfortran compiles the program and it executes both loops.
NAG's compiler claims it is illegal.

kargl[206] f95 -o f f.f90
Error: f.f90, line 9: Duplicate construct name LOOP
       detected at <end-of-statement>@LOOP
[f95 terminated - errors found by pass 1]
