	# according to ChangeLog of svn sources
	# "BTW, a quick Speedometer 4 CPU performance test showed a +15%
	#  speed increase in real addressing mode vs. direct addressing.
	#  x86 arches don't benefit much from that mode since they support
	#  complex address modes already (beyond plain load/store)."

	# According to other comments in ChangeLog the SDL support is still
	# being improved (so far was slow) and maybe still is.

	# either of these two --with-gtk=gtk1 --with-gtk=gtk2 is possible
