Compile with TDM-GCC 32 on Windows

[brynne8]

I finally successfully compiled the library on Windows with mingw32 (TDM-GCC), with some modifications. I opened this issue to see if the compilation process could be improved.

 namespace file {
 	inline FILE* open(const char* filename, const char* mode)
 	{

-		FILE* fp = nullptr;
-		fopen_s(&fp, filename, mode);
-		return fp;
-#else
 		return fopen(filename, mode);
-#endif
 	}
 }

It seems to work well but in the last step (linking)

I found the C:Program Files (x86)LuaRocks/lua5.1.dll was wrong because the backslash \ is regarded as escape character. I don't know how to change the CMake configuration, so I manually modified build.luarocks/CMakeFiles/lua-rapidjson.dir/linklibs.rsp to something like

"C:/Program Files (x86)/LuaRocks/lua5.1.dll" -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32 -loleaut32 -luuid -lcomdlg32 -ladvapi32 

And ran

C:\TDM-GCC-32\bin\g++.exe  -O3 -DNDEBUG  -shared -o rapidjson.dll -Wl,--major-image-version,0,--minor-image-version,0 -Wl,--whole-archive CMakeFiles\lua-rapidjson.dir/objects.a -Wl,--no-whole-archive @CMakeFiles\lua-rapidjson.dir\linklibs.rsp

And succeeded! The compiled dll is here rapidjson.zip
