New submission from Loic Jaquemet <loic.jaquemet+pyt...@gmail.com>:
When using xml2py from the ctypeslib codegenerator
http://svn.python.org/projects/ctypes/trunk/ctypeslib/ctypeslib/codegen/codegenerator.py
Attribute CVQualifiedType are not correctly parsed.
There are no size and align attributes.
We should use the super-type size and align attribute.
patch attached
