> FPC supports nesting of {} comments. (* *) comments do not nest, and { } comments appearing inside (* *) comments are ignored (they don't start a new nesting level). Supporting four nestable comment would require quite a few changes and I'm not sure whether this would be nice. Are these also extensions that you added yourself?
You're sure regarding (* *) comments?

=== code begin ===

program test;

(*
comment 1
(*
comment 2
(*
comment 3
*)
*)
*)

begin

end.

=== code end ===

=== compile output begin ===
