I have never included fuses to PicBasic code, always modified INC-files.
Delete line from code and check that you have following line in 16F887.INC

Code:
__config _CONFIG1, _INTRC_OSC_NOCLKOUT & _WDT_OFF & _MCLRE_ON & _LVP_OFF & _CP_OFF
Comparators are off after Power On Reset (POR), so if you haven't enabled those, then they are disabled.
