3.224 dosn't recongnize INT_COMP2 for 16F877A

Hello,
V 3.224 doesn't recognize enable_interrupts(INT_COMP2) for 16F877A. It doesn't seem ccs has INT_COMP2 for 16F877A.H, Way to work arround it?
Thank you,
Amity

There is only one interrupt for both comparators. This is explained in the
16F877A data sheet, in Section 12.6.

The following thread is about the 18F2420, but the comparator interrupts
are handled in the same way, so it has useful information:
