No, but we do need to make sure that the casual user does not
run into such issues by using the default compiler on a typical
Unix system with Python default settings.

An expert user can always use the right compiler... but then an
expert can also use the configure option :-)

gcc 4.4.2 is not exactly an old version of gcc. The perspective
of (apparently) not having the patch in in Ubuntu 10.4 LTS's
default compiler suggests that we do need be more careful about
enabling the switch per default.

Perhaps someone can report whether this affects Ubuntu 10.4 LTS ?!
