[Bug fortran/21918] New: Warnings about unused variables should point to the declaration

[schnetter at aei dot mpg dot de]

Warnings about unused variables should point to the declaration of the 
variable.  Currently the warning points to the first line of the procedure 
where the variable is declared: 
 
subroutine a (x, y) 
  implicit none 
  integer x 
  integer y 
  x = 1 
end subroutine a 
 
$ ~/gcc/bin/gfortran -c -Wall unused.f90  
unused.f90: In function 'a': 
unused.f90:1: warning: unused variable 'y'
