PCA C code contradictions

I have three seperate codes that run PCA. When I run my data through
them (or even a small synthetic data set of orthogonal variable
vectors) I get three different results.
The different codes are:
1. Accelrys Cerius2 version 4.11
2. http://astro.u-strasbg.fr/~fmurtagh/mda-sw/

Can anyone explain why differences exist and more importantly which is
the "correct" one?
