g77 should warn that 'c' might be used uninitialized, while the same code templated 
with character changed to integer or 'double precision' generates the warning. 
 
 
----test_uninitialized.f------------------------- 
c g77 -Wuninitialized -c -O  test_uninitialized.f  
c test_uninitialized.f: In subroutine `warn_integer': 
c test_uninitialized.f:15: warning: `a' might be used uninitialized in this function 
c 
c *** THERE IS NO *** 
c test_uninitialized.f:29: warning: `c' might be used uninitialized ... 
 
c     says that a might be used uninitialized 
      subroutine warn_integer 
      implicit none 
 
      integer b 
      common /xxx/ b 
 
      integer a 
 
      b = a 
      end 
 
 
c     should say that a might be used uninitialized, 
c     but doesn't! 
      subroutine warn_character 
      implicit none 
 
      character d 
      common /yyy/ d 
 
      character c 
 
      d = c 
      end
