Bummer.

on XP, with gcc 4.5.3, with this MPIR spkg. The Mac one is of course with
the Sage-provided gcc.
Just for info as it is surely unrelated, I have also always had random
segfaults while building zn_poly on my 64 bits Windows 7 Cygwin install,
with the old or the new MPIR.
It occured while doing some timings for multiplications.
After a few tries it could go through though.
There is also a problem mentioned on the zn_poly page about GCC 4.6.3 and
make tune, but I don't think we use that target anyway.
