Some of that patch should end up in the tree? I'm not sure which parts, 
though.

It seems that the version of SWIG used there is not compatible with 
Python 3.2.

This indicates some issue with AMOS and ifort. What do you get from

import warnings, scipy.special as sc
warnings.simplefilter('always', sc.SpecialFunctionWarning)
sc.errprint(1)
sc.airye(-1)

It's possible that the test is too strict.

This smells like something triggering a DeprecationWarning when GIL is 
released. If so, it should be compiler independent and reproducible on 
wine+mingw. Or, some PyCObject/PyCapsule issue.

Should be fixed in r7013
