I created this command line program:

program Test;

begin
  Writeln('I will test the TForm check now:');
  {$IF DECLARED(TForm)}
    Writeln('TForm is declared...');
  {$ELSE}
    Writeln('Apparently TForm not declared');
  {$ENDIF}
  Writeln('I will test the Forms check now:');
  {$IF DECLARED(Forms)}
    Writeln('Forms is declared...');
  {$ELSE}
    Writeln('Apparently Forms not declared');
  {$ENDIF}

end.

When I run it in a console:

$ ./Test
I will test the TForm check now:
Apparently TForm not declared
I will test the Forms check now:
Apparently Forms not declared

However in the Lazarus code editor the lines inside the {$ELSE}
clauses are shown as disabled even though these are the ones actually
present and running in the build...
