python 2.3 fails to build on ubuntu 12.04 (with workaround)

The solution was to add "BASECFLAGS=-U_FORTIFY_SOURCE" as a configure option (as seen on https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/286334).

The issue seems to occur since ubuntu intrepid, and is related to the default options of gcc -> 4.3.

pythonbrew should probably set the configure option automatically.
