modified Sys.cpp function

/**
   sys_create_dir : string -> mode:int -> void
   <doc>Create a directory with the specified rights</doc>
**/
bool _hx_std_sys_create_dir( String path, int mode )
{
	printf("_hx_std_sys_create_dir()\n");
   #ifdef EPPC
   return true;
   #else

   hx::EnterGCFreeZone();
#ifdef NEKO_WINDOWS
   //bool err = mkdir(path.__s);
   std::wstring temp = _Win32Utf8ToUtf16( path.__s );
   bool err = _wmkdir( temp.c_str() );
#else
   bool err = mkdir(path.__s,mode);
#endif
   hx::ExitGCFreeZone();

   return !err;
   #endif
}

this has to go up top

#ifdef NEKO_WINDOWS
// Do not use outside win32
	inline std::wstring _Win32Utf8ToUtf16(const std::string& str)
	{
		printf("TESTING\n");
		std::wstring convertedString;
		int requiredSize = MultiByteToWideChar(CP_UTF8, 0, str.c_str(), -1, 0, 0);
		if( requiredSize > 0 )
		{
			convertedString.resize(requiredSize);
			MultiByteToWideChar(CP_UTF8, 0, str.c_str(), -1, &convertedString[0], requiredSize);
			convertedString.pop_back(); //remove NULL terminator
		}
 
		return convertedString;
}
#endif

Line 14 can be removed.
The printf calls too.
temp could have been const.
Otherwise, Looks Good To Me 👍
