Natural signs in accidentals

[Benjamin Esham]

Maybe this is addressed in the documentation, but I didn't see it 
anywhere,
so I'm asking here.—Anyway, consider this music snippet:

  \key a \major    % three sharps: F#, C#, G#
  ges'1

The G-flat is displayed with two accidentals: a natural (which I assume 
is
supposed to cancel the sharp in the key signature), and then the flat.  
I'm
wondering if there's any way to prevent the first natural from 
displaying.

I realize that American concert band music may not be the pinnacle of
beautifully-engraved music :-P, but I'd still like to get rid of that 
natural.
Is there any way to do that?  Thanks.
