1.6.2RC1 builds fine under the following configurations (all of them
x86_64):
* Ubuntu Lucid 10.4 / Python 2.6.5 / GCC 4.4.3: OK (KNOWNFAIL=3, SKIP=5)
* Archlinux (as of today) / Python 3.2.3 / GCC 4.7.0: OK (KNOWNFAIL=5,
SKIP=5)
* Archlinux (as of today) / Python 2.7.3 / GCC: OK (KNOWNFAIL=3, SKIP=5)
Great work!
Andreas.
