actually, there is a bug in the test for the "void_novoid" test - when
using the right variables it also uses the unaligned stores.
   
   what happens if you make store_ptr() not an inline?

then store_ptr becomes a real function that uses unaligned stores,
probably working.  i wonder the effect this has on program startup
since it generates between 7 and 10 extra instructions (including
a branch & return.)
