gfortran: enabling specific warnings for a used but not set variable, and a set but not used variable

[Laurent IBGUI]

Dear Madam, dear Sir,

I am intensively developing scientific codes in Fortran. In particular, I use gfortran. Would it be possible to include in gfortran the following features that are available in the non longer updated (as it appears) g95 compiler:

 warning (113) in g95: a variable is used but not set, i.e., uninitialized (case of i below):
 warning (112) in g95: a variable is set but never used (case of j below)    (-Wunused-but-set-variable   does not provide any message with gfortran 5.3.0)


      IMPLICIT NONE
      INTEGER(kind=4) :: i,j

      print *, 'i =',i
      j = 0

      END


Thank you so much for your help, and also, for the great work you are doing with this gfortran and gcc extremely useful project.

Best regards,
Laurent Ibgui.
