What do you mean by an 'mIRC compiler'? As I know it, there are no plans to release sub-programs of mIRC, as Khaled spends all his time on mIRC, I believe this is pointed out in his
personal FAQ.
Do note, Khaled very rarely releases information about what will be in the next version of mIRC, or what is on his 'to do' list. We could not say what Khaled plans to do - just what is likely (or rather, unlikely).
