C compilers for Windows are available relatively cheaply at ;-)

Yep. I've just sent 0.9.2 binaries to the maintainer and I think they'll show
up there soon. Btw. these binaries are the same I have on my homepage.

You're not a true hacker :-P Else you'd have looked at the HTML code and seen
that the download link was only commented out. The reason was that they
depended on a libz.dll which normally isn't available on Windows systems:

I've been trying to get away from MSVC++ for building Free Software like MySQL.
Unfortunately, MySQL cannot be built out of the box using mingw on Windows, so
I needed to use a third-party patch against MySQL to get at least the MySQL
client libraries built.

Building MySQLdb (the Python adapter) itself using mingw is no problem
afterwards. But unfortunately, the MySQL client library I built was for some
reason dynamically linked against a libz.dll, which caused problems for Windows
users. Which is why I (and Andy) pulled back the previous 0.9.2 binaries.

After a very loud aaaaaaaaaaaaargh and a month later I've now given in and
built statically linked MySQLdb 0.9.2 binaries with MS Visual C++. And removed
the HTML comment on my homepage ;-)
