PARI must have exhibited some bugs. The question is how/why/if this is
still needed.

-march=core2 using the latest gcc and that seems to work fine.
The answer is at #7092: because of a failure to build pari with gcc-4.4.1

-O1 instead of -O3. Is there not a way to detect that particular
compiler-distro combination? Otherwise all Linux users suffer!
