==============  RELEASE 0.3.6  ==============

20051008	The bug was not because of faulty ARM documentation after all,
		but it was related to those parts of the code.
		Fixing the RTC (dev_mc146818) to work with CATS.
20051009	Rewriting the R() function; now there are 8192 automatically
		generated smaller functions doing the same thing, but hopefully
		faster. This also fixes some bugs which were triggered when
		trying to compile GXemul inside itself. :-)
		Adding a dummy dev_lpt.
20051010	Small hack to not update virtual translation tables if memory
		accesses are done with the NO_EXCEPTION flag; a time reduction
		of almost a factor 2 for a full NetBSD/cats install. :-)
20051011	Passing -A as the default boot arg for CATS (works fine with
		OpenBSD/cats).

==============  RELEASE 0.3.6.1  ==============
