Questions about bool or sal_Bool in Any::setValue, makeAny

[Matteo Casalin]

Hi all,
     I was converting all sw call-places to Any::setValue that pass 
sal_Bool to use bool instead. I wonder if this is a good choice or not, 
is there any guideline?
Also some of these call places look like:

     sal_Bool bTrue = sal_True;
     uno::Any aVal(&bTrue, ::getBooleanCppuType());
     some_function_call( aVal );

or

     uno::Any aAny;
     sal_Bool bFalse = sal_False;
     aTmp.setValue(&bFalse, ::getBooleanCppuType()  );
     some_function_call( aTmp );

could these be changed to use makeAny(bool)? Does this hold also if the 
same Any object is used multiple times (each time calling setValue on it)?

Thanks
Matteo
