There is something wrong in combine_predictions_for_insn(). Perhaps stack gets

a) Only allow certain kinds
b) Allowing all kinds and doing the conversion/providing the needed functions.

Also seems to affect process.destroy() somehow. The "DONE" is not printed
after the destroy call on gcj win32, but is on Sun.

libgfortran/io/intrinsics.c provides flush_i8, but that one is never used.

The "problem" described in comment #1 depends on the default integer kind.
