Initial Comment:
Hi Martin,

unfortunately I haven't found time to work on a C based
winerror module. 

Here's a generator and the generated Python module
which defines the interface. This can then later be
replaced by  a more efficient C implementation.

It's a new module, so it may also come with a new interface. 

Note that there's not much difference between the errno
module and winerror, except that you can't write
winerror.ERROR, but have to do one more indirection:
winerror.winerror.ERROR.

The reason for having a lookup object is that the number of
error symbols is huge and you'd ideally only want those
symbols being loaded into the process that actually need
(typically only a few). The C implementation of the lookup
object will make this possible by storing the data in a
static C array.

I will add documentation for the module based on the errno
module documentation, but not before next week - no time. I
still think that the module should go in before beta1 is
released.

As discussed before, I am uncomfortable with a lookup
object, instead of just two dicts or dict-like objects: it's
inconsistent with the errno module, and I don't see the need
for it.

Also, can you please provide documentation?
