It works, thanks.

Still on the portability issue, I have some doubts about the following
hack, to create an output file of the same type as the input one:

SUFFIXES = .png .small.png

.png.small.png:
        convert -geometry $(SMALL_WIDTH)x$(SMALL_HEIGHT) $< $@

I didn't found any failure yet, but I'm not 100% sure it will work
everywhere.
