[Bug fortran/29625] New: Octal edit descriptors allow real variables, even with -std=f95

["brooks at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

(Fortran version: GNU Fortran 95 (GCC) 4.2.0 20061015 (experimental))

Consider the following program:

~/temp/gfortran> cat trans1.f90
    program trans1
      real :: a
      a = 1.
      write (*,"(10x, f9.5)" ) a
      write (*,"( 1x,  o20)" ) transfer(a, 0)
      write (*,"( 1x,  o20)" ) a
    end

According to the Fortran 95 standard (section 10.5.1.1), the output list item
corresponding to an "O" edit descriptor shall be of integer type.  Although
allowing real items is a perfectly reasonable extension when strict
standard-conformance is not requested, when strict standard conformance is
requested, the last of these write statements should produce an error. 
However, it does not:

~/temp/gfortran> gfortran -std=f95 -Wall trans1.f90 -o trans1.exe
~/temp/gfortran> ./trans1
            1.00000
           7740000000
           7740000000
