ANN: 2.0.4 win32 build using mingw32

[Mauro Cicognini]

Hi all,
I finally got around to updating my win32 binary of Python-LDAP.

The reason it took so long was that in between my last attempt and today 
the core OpenLDAP developers have dropped MSVC support and now Win32 
platforms are officially supported through mingw32, so all my previous 
work of making Python-LDAP compile using the Microsoft toolchain were 
useless and obsolete :-(

The good news is that the original developer of the OpenLDAP win32 port  
(his name is Lucas Bergman) resumed work on it, as a purely volounteer 
effort, so now we can count on OpenLDAP living on Windows for a while. 
So far his most important achievement has been the re-introduction of 
SSL capabilities (which should be promptly available through Python-LDAP 
too).
On the other hand, the SASL developers seem to be sticking to the MS 
toolchain, therefore since mingw cannot build it, SASL support is not 
available instead... oh well. I sure hope we'll have it back sometime, 
but that isn't currently one of my priorities.

After asking the win32 Python developers for reassurance (it turns out 
mingw-built extensions will work nicely with the ordinary MSVC-built 
interpreter), I had to learn to use mingw32, which was fun (I got around 
building OpenLDAP too) and actually easier than I thought. I used the 
very latest versions of both OpenLDAP (2.2.18) and OpenSSL (0.9.7e) so 
we should really be cutting edge.

Anyway, I have uploaded the new binary to my homepage (the one referred 
to from http://python-ldap.sourceforge.net/download.shtml) where it 
should appear sometime tomorrow.

I also have a mingw setup.cfg for our build script, which I propose to 
label the "official" win32 compiler, and therefore to remove all 
MSVC-related stuff from the HEAD branch of the source tree. I can 
provide the script on demand, I won't obvisouly attach it here to avoid 
spam.

I'd be glad to hear feedback, although, as always, YMMV.

All the best,
Mauro
