Hi Ioannis,
I can't help you with the file as I'm on v8.85 myself but why not change your CONFIG to & _BORV_HI? That should be the same thing as _BORV_25 as far as I can see. Or if you "must" stick with your current syntax add
Code:
_BORV_25         EQU  H'FBFF'    ; Brown-out Reset Voltage (Vbor), high trip point selected.
to the current .INC file? Doing the later will of course be "reversed" the next time you update.

/Henrik.
