--- Comment #2 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
Apparently only for implicitly-typed variables.

This works as expected:

program main
  integer, bind(c) :: i
end program main
$ gfortran a.f90 
a.f90:2:23:

   integer, bind(c) :: i
                       1
Error: Variable 'i' at (1) cannot be BIND(C) because it is neither a COMMON
block nor declared at the module level scope
