yes indeed I had a huge fight with mysqldb driver because of this. Since the
windows version of mysql is compile with VS2003 and python too getting those
drivers to build with gcc will require recompiling everything and making it
incompatible with the stock mysql.

This is something that shock me a lot, why python (the official) on windows
is build with a tool that is not accessible to all developers. Building
extensions on windows is just a pain...
