To save repeating myself, see the detailed reply I just posted on thread "PIC12F629 w/ Internal Oscillator"... There's got to be an FAQ added to this board sometime...

@ DEVICE XT_OSC

or

@ DEVICE pic12F675, XT_OSC

Defines without @ don't work (other than PBP defines listed in the manual) - compiler just ignores erroneous ones without flagging any error (that includes ones from the PBP manual that you've done a typo on... so make sure you spell them right!).
