Using FPC v2.6.3 the {$WARNINGS OFF}, {$HINTS OFF}, and {$NOTES OFF} directives affect all subsequently compiled units as well. That seems wrong. Delphi limits the effects of those to the current compilation unit, which is what I'd expect. Is this intentional?
Sample code:
---- Test.dpr ------
program Test;uses
Unit1 in 'Unit1.pas',
Unit2 in 'Unit2.pas';begin
end.
---- Unit1.pas -----
unit Unit1;
interface
implementation
var
Var1: Boolean;
end.
---- Unit2.pas -----
unit Unit2;
interface
implementation
var
Var2: Boolean;
end.
-------------------Compiled with
fpc Test.dpr
Produces this output:

But if I add a "{$NOTES OFF}" declaration just before the "var" block in Unit1.pas, the output is instead:
