This will fail on intel if you are not importing ImageAndTextCell.h in
this source file, in which case you would also see a warning for this
line.
The compiler on both ppc and intel will assume that the alpha
parameter is a double if it doesn't see a declaration for the method.
Due to coincidence in the way arguments are passed, it would work
anyway on ppc, but if you were to set a break point on
-[ImageAndTextCell setImage:alpha:] on intel you'd always see 0.0
passed in as the alpha value.
Basically, if you're seeing warnings, get 'em fixed and see if the
problem clears up.
