            Bug ID: 66159
           Summary: bogus warning for alias-declaration using
                    elaborated-type-specifier
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED
          Keywords: diagnostic
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: redi at gcc dot gnu.org
  Target Milestone: ---

struct X { };

typedef struct ::X x1;

using x2 = struct ::X;


t.cc:5:21: warning: declaration ‘struct X’ does not declare anything
 using x2 = struct ::X;
                     ^

The two forms should be equivalent.

--- Comment #4 from Arjen Markus <arjen.markus895 at gmail dot com> ---
I had a probably related failure with the following program using 4.9.2 under
Cygwin.

The program:

! chk_alloc_string.f90 --
!     Check if allocatable-length strings work in principle
!
program chk_alloc_string
    implicit none

    character(len=:), dimension(:), allocatable :: strings
    integer :: i

    allocate( character(10):: strings(1:3) )

    !strings = [ "A", "C", "ABCDE", "V" ]
    strings = [ character(len=4) :: "A", "C", "ABCDE", "V" ]

    write(*,*) len(strings(1)), size(strings)
    write(*,'(a)') strings
end program chk_alloc_string

The output:

           4           4
ACAV
CAV
AV
V

where I expected:
           4           4
A
C
ABCD
V
