The default studio 2008 sdk is 6.0a.  7.0 is needed.  Steps to making it build:
1. install .net 4 and windows sdk 7.1
2. set 7.1 as studio default
3. open a new shell
In general the environment is the same as 'Chromium Build Instructions'

It would be nice to have the option to build with 6.0 sdk or no WIC support.

This is a similar problem to mingw which is missing this value as well. That 
case works because INITGUID is defined ensuring the GUIDs are explicitly 
defined rather than declared extern.
Using this solution for v6.0 reveals the #ifdef _GUID* checks for these values 
are bogus...DEFINE_GUID defines a variable. Need to find a better way to work 
around this.
