would that lead to a warning if the definition does not exist.  This pattern is used in many
places in our source code.  One usage, that might apply in this case, is to temporarily activate
a debug feature by passing additional arguments to the compiler via environment variables.
  In my opinion that is a valid use of otherwise never defined variables.

the code looks like this:

void SwCrsrShell::FirePageChangeEvent(sal_uInt16 nOldPage, sal_uInt16 nNewPage)
	if( Imp()->IsAccessible() )
		Imp()->FirePageChangeEvent( nOldPage, nNewPage );

ACCESSIBLE_LAYOUT is not defined. Thus compiler has:

void SwCrsrShell::FirePageChangeEvent(sal_uInt16 nOldPage, sal_uInt16 nNewPage)

and thus warns about not used arguments nOldPage, nNewPage.

This warning is minor warning, the real question is why we have #ifdef'ed code on something
that is never ever mentioned/defined elsewhere...
