[Bug fortran/37863] New: Display of a value close to 1 shows 2

["sylvestre dot ledru at inria dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

With the code here:
----
      program pb
      character*10 form
      character*4093 str
      str=' '
      write(form,120) 3,0
      write(str(1:3),form) 1.0d0 - 1.110223024625157D-16
      print *,str(1:10)
 120  format('(f',i2,'.',i2,')')
      end
----

Compiled with gfortran 4.3.2:
the output is 2

With the gfortran 4.2.4
the result is 1 (which is the right one)

$ gfortran-4.3 -o pb pb.f && ./pb 
  2.       
$ gfortran-4.2 -o pb pb.f && ./pb 
  1.
