As reported by Fran,cois-Xavier at
http://gcc.gnu.org/ml/fortran/2010-08/msg00484.html

a)

  integer(kind=8) :: i
  i = 0
  print *, kind(ior (i, z"ff1e"))
  print *, kind(ior (0_8, z"ff1e"))
  end

gives different different results for the compile-time and run-time evaluation.

b) F2008 allows BOZ in bit intrinsics, which need to be properly handled; for
IOR(I,J) one has:
* I or J can be BOZ or integers, but they can't both be BOZ.
* "Result Characteristics. Same as I if I is of type integer; otherwise, same
as J."
