Open P16F88.INC in your MPLAB directory and look under the INTCON Bits section.

Code:
;----- INTCON Bits --------------------------------------------------------
GIE                          EQU     H'0007'
PEIE                         EQU     H'0006'
TMR0IE                       EQU     H'0005'

INTF                         EQU     H'0001'
RBIF                         EQU     H'0000'
It's defined as TMR0IF. You can fix this with;

Several of the newer 16F header files have it listed both ways.
