Strange. We use GCC 4.2 for all prebuilt archives on Linux and
have never run into such problems.

I can only imagine that the Python binary you are using was
built using GCC 4.0 and an old XCode version. This would leave
traces of the used GCC options in Python's Makefile (which gets
installed as part of the Python install process). The Makefile
is then used by distutils to build extensions.
