           Summary: Incorrect field alignment with Gw.dEe descriptor
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: libfortran
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: thenl...@users.sourceforge.net


With a Gw.dEe descriptor the output is formatted incorrectly if the F
conversion is selected and an exponent width e>4 is selected.

The conversion in this case is F(n-4).(d-x).n('b')

The constant n is required by Fortran 2008 to be e + 2.

But it is incorrectly calculated by GFortran as min(e, 4) + 2

print "(g15.3e5)", 0.1d0
print "(g15.3e5)", 0.1d12
Output:
    0.100
   0.100E+00012

Expected output:
   0.100
   0.100E+00012
