MSVCRT.DLL is the MinGW (and Visual Studio 6/1998) runtime. Visual 
Studio links against a different runtime depending upon which version 
you use (and there is a different runtime for every version VC 
2002/2003/2005/2008/2010/2012 plus often for each service pack).

Generally, I think the best thing would be to find out where LuaSocket 
is going wrong and modifying it to not care about the C Runtime that Lua 
is built with.

Identifying the runtime would involve looking at the DLLs linked against 
the lua.dll that the application uses.
