Do compiler warnings create yellow blocks?  There are other warnings on other machines
as well.  OTOH, testing ctypes (see below) can cause core dumps, these should create
orange blinking blocks ;-)

You can do it faster then me, I assume - so go ahead and check it in.
I'll backport it to the upstream ctypes CVS repository.

It was caused by a test that did access misaligned integer fields in a structure.
ctypes isn't yet able to handle this, but probably should steal the code for it
from the struct module.  But the change is not trivial I fear because of the
access macros that also handle bit fields in structures.

And I never had tried it before on a sparc machine - all the intel and ppc processors
seem to have no problems with it.
