bug in NINT() in gfortran

[Hans Jørgen Aagaard Jensen <hjj at ifk dot sdu dot dk>]

The NINT() intrinsic in current gfortran under cygwin has a bug. Below follows:
1) small test program
2) output from this program
3) output from "gfortran -v"

(I am not submitting this to the gcc bugzilla, because the test worked OK on all the linux systems I tested.)
(I found the error becaus our quantum chemistry softward dirac (http://dirac.chem.sdu.dk) failed a few of the internal tests.)

======= 1) small test program ============
      program test
      double precision xval
      xval = 132843.61283756854D0
      do i = 1,7
         ipoint = nint(xval)
         write (6,*), xval, ipoint
         xval = 10.0d0*xval
      end do
      return
      end
======= 1) output =============
   132843.61283756854           132844
