Which compiler do you use?

Have you first acquainted yourself with the RC5 format? https://www.sbprojects.com/knowledge/ir/rc5.php

Looking at the code and register names, I'm quite sure it's PIC and not AVR.

Are you sure? The file rc5_decoder.c has a line

Code:

ANSEL &= 0xfb;  /* RA2 as digital I/O */

So, it can't be 16F877A, because 16F877A does not have ANSEL register.
