I have now fixed this problem (but not the macro problem which I am leaving
to Andrew for final decision since I don't know whether or not that macro
would actually work with libgd 1.8.4 with -drvopt optimise).  But if you cv=
s
update and work around the gdImagePalettePixel problem by adding the macro,
I think you will find the above problem will be gone.

BTW, Andrew, I have just checked your recent changes, and eveything seems
to be fine; x08c gives good results with
no drvopt and with
-drvopt text,smooth,24bit and
-drvopt text,smooth.
