ES formatting messed up?

[Steve Kargl]

program a
   real(8) x
   x = 1.2345D-280
   write(*,'(ES14.6)') x
end program a

troutmask:kargl[257] gfc --version
GNU Fortran 95 (GCC) 4.1.1 20060302 (prerelease)
troutmask:kargl[259] gfc -o a a.f90
troutmask:kargl[260] ./a
  1.234500-280
 
Why is the E missing in the output?  Shouldn't ES14.6
give a width of 14 characters:  s1.234500E-280 where
s is the optional sign.
