AngelScript will no longer run on Windows XP (using VS2013 and the v120 Windows XP platform toolset). The project builds fine, but when loading on Windows XP there is a link error attempting to find InitializeCriticalSectionEx in kernel32.dll (I think).
I found that in order to maintain compatibility with Windows XP I needed to define a special preprocessor macro indicating the WINXP target. I used "AS_WINXP" for this purpse. You will see it in the attached patch.
