Hey @abit, I am not familiar with Github. I did create a branch vs2013 with modification and push to Github. I did a pull request and then I closed it because I thought it will merge with my fork, not the original develop branch. And also it appears that dan created vs2013 branch 23 days ago. I need more time figure this out.

Update:
I created another branch called win_steem and pull request(#496) it.
Please review it when you have a chance. Thanks for your help.
