What else would you expect given that the F2003 standard states:

   If a data-stmt-constant is a boz-literal-constant, the corresponding
   variable shall be of type integer. The boz-literal-constant is treated
   as if it were an int-literal-constant with a kind-param that specifies
   the representation method with the largest decimal exponent range
   supported by the processor.

Previous versions of gfortran may not have had the ability
to see the conversion.
