Why not replace all the compiler directives, which are unknown to the 
Delphi compiler, by a common different format, like {#PRAGMA WARN...}, 
and implement a general Pragma subsystem, where the FPC people could add 
the functionality later, if this part is too time consuming for a 
student project?
