I think there is a confusion here. The dialects listed here:

  Free Pascal dialect (default)  
  FPC mode with Object Pascal support  
  Delphi 7 compatibility mode  
  TP/BP 7.0 compatibility mode  
  Macintosh Pascal dialects compatibility mode  

are *not* supersets of any of both ISO Pascals. They are merely supersets of a "Hello World"-size subset of these ISO Pascals.
You don't need to go too far into details: the modularity is fully incompatible. What is called "unit" in the descendants of UCSD Pascal listed above is called "module" in ISO 10206 and... nothing at all in the previous ISO 7185. It is not just syntax: the rules for "uses"-ing a "unit" are completely different of those for "import"-ing a "module"...
