mysql2 runs successfully again

after the version 0.2.11 or 0.3.6, mysql2 runs successfully again.

And I introduce the way to run rails 3.0.9 with mysql2 0.2.11 on MariaDB 5.2.7 in Windows.

1. Install the MariaDB on Windows into C:/MariaDB
2. Install ruby 1.9.x with Ruby DevKit 4.5.1
3. Install rails 3.0.9
4. Install mysql2 0.2.11

   > gem install mysql2 --version=0.2.11 --platform=ruby -- --with-mysql-include=C:/MariaDB/include --with-mysql-lib=C:/MariaDB/lib

5. Do rails ways

   > rails -d mysql sample
   > cd sample
   > rails g scaffold person first_name:string last_name:string
   > rails s

That's all.
