Oh, so it is already implemented :-)
same here:

12 1N 1) I := 0 ;
13 1N 1) while not ( EOF ( INPUT ) ) do
the (*$N+*) comment switches on the nested comment option
in line 10 you can see a nested comment using (* ... *)
no warnings
it looks a bit archaic, but remember: it is a compiler which has it's origin
in the 1970s.
Kind regards

Comments of different types can be nested;
comments of the same type can be nested, if the compiler option N+
is set.
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?
