It seems that there are two problems here:
- First, there is a bug in the sys.flags structure: revision 62322
added a new flag in the underlying C structure, but did not increase
the number of fields visible from python code. This should be
corrected: in sysmodules.c, the number in the flags_desc initializer
should match the number of items in flags_fields.

- Then, it seems that warnings.py could not import the C-based
"_warnings" module. Could you modify warnings.py and remove the
"except ImportError" clause to see why?
