I've found it. The RTEMS sources claim the "PowerPC 602" to have 4byte floats,
only.

Cf. gcc-4.0-branch/fortran/trans-types.c ca. line 228ff:
/* F95 14.6.3.1: A nonpointer scalar object of type double precision
real ... occupies two contiguous numeric storage units.
...
.. But at present there are
no GCC targets for which a two-word type does not exist, so we
just let gfc_validate_kind abort and tell us if something breaks. */
Well, the h8300 has 8byte types (seemingly long long), but it doesn't have 8byte
floats. As the comment is on REAL8, ... there is something fishy in there.
