JTAG Vcc pin on coolrunner

[maxfoo]

For the xilinx xc2c256 cpld tq-144 package, when connecting to a jtag header,
according to the table in the datasheet pin 8 is Vaux(jtag supply).
My question is do you need to connect the other vcc pins too, 1,37,84,etc...
or is pin 8 the only one needed? On the xc9572 all vcc pin are connected
together...

TIA

Forget it, I figured it out for myself, if anyone's interested in my conclusion
email me. If not... bye bye!
