> 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/.

this needs to be tested on every platform Sage supports, (itaniums, macs,
sparcs...).
This is quite a drastic change, and there is no telling how older versions
of gcc would cope!
I think it should get seen by real GAP kernel folks before we start even
think of shipping this.
Should I post this on GAP-support, of which I happen to be a member?
Finally, I do not understand why it is a blocker. Is 4.4.1 going to
support gcc-4.5.0 ?!
I would say that attempting to support gcc-***.0 is a waste of time.
Let it ripe to at least .1 or better .2...
I therefore lower the priority of this to major.
I would also propose another way to get it in Sage: make these new
patches conditional on gcc version >=4.5.
