> > Building on Dima's new p2 from #8774, I created a p3 that avoids the
strict aliasing problems by cleaning up some of the code. I also un-pre-
applied saveload.patch in src/, and cleaned up a number of files in
src/tst/ (including the large {{{src/tst/GAP\ 4\ PPC}}}) which were
somehow copied from src/.
