Vladimir Marangozov fixes an AIX-specific problem, writing: """ Following up Robin Dunn's troubles with freeze, here's a patch that fixes an oddity regarding the import logic of shared modules on AIX. Symbol resolution of shared modules is now handled properly for the cases when the python library is linked to a binary with an arbitrary name. This includes the standard python[version] executable, but also applications that are embedding the python core (i.e. linked with libpython[version].a, the latter being static or shared). """
