[Bug fortran/34771] New: Parenthesis around character variables: No expression

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

(c) and c
are regarded as the same for character variables; for other types (z) and z are
not the same.

gfc_get_parentheses (gfc_expr *e)
{
  gfc_expr *e2;

  /* This is a temporary fix, awaiting the patch for various
     other character problems.  The resolution and translation
     of substrings and concatenations are so kludged up that
     putting parentheses around them breaks everything.  */
  if (e->ts.type == BT_CHARACTER && e->ref)
    return e;

Test case:

subroutine a(c)
  character :: c(*)
  call b((c))
contains
  subroutine b(y)
    character :: y(*)
  end subroutine b
end subroutine

Due to the parenthesis, it should print:
"Error: The upper bound in the last dimension must appear in the reference to
the assumed size array"

(Error messages needs patch for PR 34665.)
