Compilation warnings with 'cpp-input'

[Philippe Schaffnit]

Hi!

First of all, sorry if this is already known...

I think this was working properly before (when?), but '-x f95-cpp-input'
seems to damage compilation warning (locus?), one can live with it, but
as long as '-cpp' isn't working yet, this is a bit annoying...

Should I file a PR for this?

Thanks!

Philippe

PS:

cat Check_Warnings.f90

      PROGRAM Test

      IMPLICIT NONE
!
      INTEGER ::   Junk_1, Junk_2, Junk_3
!
      Junk_1 = Junk_2
!
      END PROGRAM Test
!


gfortran -g -Wall -O1 -x f95-cpp-input -c Check_Warnings.f90
