These tests fail on systems where the high bit of the address where
the process stack pointer resides is set.  Loop.c turns a signed
comparison into an unsigned one, but doesn't adjust all the
assosciated RTL along the way.  Loop requires quite a bit of surgery
to fix this, the bug is well understood though.
