Based on brian's input, here is the command line size allowed in Windows.

MS DOS command.com	 127
Windows NT cmd.exe	 256
Windows 2K cmd.exe	2046
Windows XP cmd.exe	8190

I use Windows XP, not sure why it still limits to 126 for tar.exe?

Thanks. Just think if will be more nice if it can work out without using 
those utilities.
