I thought one of the latest commits made the .sln compatible with 2005 
(r86 & r87), but it looks like that's not the case.
Unfortunately, I cannot test 2005 or 2003 on my end, so I will be 
relying on users like you to let me know what works and what doesn't.

OK. I think my initial workaround was lame, because actually neither 
2005 or 2008 seem to have _WIN32_WINNT_WIN7 defined in the first place.

I believe then that if you replace the above with the following, 
everything will work as expected:

#if defined(_MSC_VER)
#if !defined(_WIN32_WINNT_WIN7)
#define _WIN32_WINNT_WIN7 0x601
#endif

Then on Windows 7 platforms, people will probably need to add a #define 
WINVER 0x601 in their preprocessor conf, but that's another story.

Can you try that and let me know?
