erroneous warning about line truncation

[Hans Horn]

Folks,

I get warnings about line truncation on fixed-form (f77) code when I 
have inline comments starting at column 73 and beyond.

I mocked up this little piece of silly code to demonstrate:

       subroutine foo
       IMPLICIT NONE
       Integer stupid_dummy_variable1 ! stupid_dummy_variable1
       Integer stupid_dummy_variable2 
! stupid_dummy_variable2
       Integer stupid_dummy_variable3 
  ! stupid_dummy_variable3

       write(*,*) stupid_dummy_variable1,
      &           stupid_dummy_variable2,
      &           stupid_dummy_variable3

       end

Compiling it gives:

$ gfc -Wall -c foo.f
foo.f:5.72:

       Integer stupid_dummy_variable3
                                                                         1
Warning: Line truncated at (1)
