But then we only move the problem: people who want to build universal
numpy extensions will have the wrong value, no ? The fundamental point
of my patch is that the value is set whenever ndarrayobject.h is
included. So even if I build numpy on PPC, NPY_BIGENDIAN will not be
defined when the header is included for a file build with gcc -arch
i386.
