what for does gcc need ~590MB of memory on ppc? 
on ix86 it works fine.

Hmm, the preprocessed source will no longer work on the mainline because of changing how the altivec 
intrinsics work.  In fact the preprocessed source is not even complete which makes this a dup of bug 
19411.

Use tempary variables,
instead of doing something like:
  vec_add(vec_add (a, b), vec_add (c, d))
do:
  temp = vec_add (a, b);
  temp1 = vec_add (c, d);
  vec_add (temp, temp1);
