Seemingly the following code snippet cannot be compiled with the current GPC version:

Unit Foo;

Interface

Function Bar: integer;

Implementation

Function Bar = result: integer; begin (* Bar *) result:= 2; end (* Bar *);

end.

This results in a 'Header does not match previous definition' for function Bar.

Yes, according to the standard (*), the result variable must be present in the original declaration as well. GPC didn't check this before, but does now.

(*) This is only stated in the Object-Oriented Extensions, 6.7 (d):

: [...] and if one function definition contains a result variable : specification, then the other also has a result variable : specification of the same spelling.

It is a suggested change for an Extended Pascal revision (cf. 6.13). Whereas EP itself doesn't allow repetition of the function-heading at all, so you'd have to write (apart from using a module vs. a unit):

Unit Foo;

Interface

Function Bar = result: integer;

Implementation

Function Bar; begin (* Bar *) result:= 2; end (* Bar *);

end.
