Installing luasql 2.2 with luarocks onto lua for windows install - lua

Question

So it turns out lua for windows install has some earlier 2.1 version of luasql on it, and I need to be able to use luasql 2.2 (particularly mysql). I've spent all day trying to install this thing with luarocks but keep hitting a wall. This is the 3rd wall I've hit but the first one that I just have no clue where to even begin.
I run: luarocks install luasql-mysql MYSQL_DIR="E:/Programs/MySQL/MySQL Server 5.5"
It goes through and outputs (removing a lot of the output where it's just repeating the same thing but different file):
Extracting luasql-2.2.0\src\jdbc
Extracting luasql-2.2.0\src\jdbc\Makefile
... (lots of these here)
Extracting luasql-2.2.0\vc6\sqlite.def

Any idea where to start? I've had to a) install standalone mysql (was previously using one that came with WAMP since I was already using that before), and b) install visual studio 2010 (c# and c++ versions so far), and c) use visual studio command prompt to run the luarocks stuff, if I use regular command problem it breaks way before this.
I'm hoping this is an easy issue to fix for someone familiar with compiling C which is what this seems to be doing.

Add the following to ls_mysql.c after line 17:
#include <windows.h>
So that windows.h is included after winsock.h and before mysql.h.
