This is the case in some sense:  You get warnings when you use compiler
directives together with `--standard-pascal', `--extended-pascal', or
`--object-pascal'.  Use `--pedantic-errors' to turn these warnings into
error messages.

How can you check whether they really use the `--extended-pascal' switch?
You have to stand behind them and watch what commands they type to compile.
What about just saying them that they must not use compiler directives?

BTW, the `--pedantic' switch is intended to check whether some code
is *completely* portable.  With `--pedantic', you get warnings about
everything for which a Pascal compiler is known not to accept it.
(* Read:  You get warnings about just *everything*. :*)
