Hm.  I don't like the #define.  And Java doesn't initialize
long_integer_type_node either, so I think the patch won't fix
the bootstrap issue.  Basically the C kind types are not
really supposed to be used in the middle-end.

What you probably want is to use
smallest_mode_for_size (type_precision + 1, MODE_INT)
and fail if that returns BLKmode (ugh, it doesn't ...).
From the modes precision then build a type using
build_nonstandard_integer_type. And possibly you
want to restrict yourself to maximum BITS_PER_WORD
size to avoid long long or TImode arithmetic.
