EDIT: Oh and it seems that TLS was introduced into warcraft III in patch 1.22

Warcraft 3 always used the Thread Local Storage, what makes you thinking it was introduced into Warcraft with the Patch 1.22?

/EDIT:

You can access other Threads Local Storage with this code:

__declspec(naked) DWORD GetCurrentTEB()
{
	__asm
	{
		mov eax,fs:[0x18]
		retn
	}
}

DWORD WINAPI TestThread(LPVOID pParam)
{
	printf("TEB of this Thread 0x%x\n", GetCurrentTEB());

	bPrinted = TRUE;

	while(TRUE)
		Sleep(1000);

	return TRUE;
}

INT main()
{
	CreateThread(NULL, NULL, TestThread, 0,0,0);
	
	while(!bPrinted)
		Sleep(1);

	// Enumerate all Threads in this Process ..!
	HANDLE hSnap = CreateToolhelp32Snapshot(TH32CS_SNAPTHREAD, GetCurrentProcessId());
	
	THREADENTRY32 tEntry;
	tEntry.dwSize = sizeof(tEntry);

	if(Thread32First(hSnap, &tEntry))
		do {
			if(tEntry.th32OwnerProcessID != GetCurrentProcessId())
				continue;

			HANDLE hThreadHandle = OpenThread(THREAD_ALL_ACCESS, FALSE, tEntry.th32ThreadID);

			if(hThreadHandle == INVALID_HANDLE_VALUE)
				continue;

			printf("Thread-Id 0x%x, TEB 0x%x\n", tEntry.th32ThreadID, GetTEBFromThread(hThreadHandle));
		} while(Thread32Next(hSnap, &tEntry));

	CloseHandle(hSnap);

	return NULL;
}

TEB* GetTEBFromThread(HANDLE hThread)
{
	pfnNtQueryInformationThread NtQueryInformationThread = (pfnNtQueryInformationThread) GetProcAddress(LoadLibrary("ntdll.dll"), "NtQueryInformationThread");
    THREAD_BASIC_INFORMATION tbi;
    THREAD_INFORMATION_CLASS tic = ThreadBasicInformation;

	if (NtQueryInformationThread == NULL)
        return NULL;	

	if (NtQueryInformationThread(hThread, tic, &tbi, sizeof(tbi), NULL) == NULL)
		return (TEB*)tbi.TebBaseAddress;

	return NULL;
}

Hope this helps
