20070324	Adding a "--debug" option to the configure script, to disable
		optimizations in unstable development builds.
		Moving out SCSI-specific stuff from diskimage.c into a new
		diskimage_scsicmd.c.
		Applying Hĺvard Eidnes' patch for SCSICDROM_READ_DISKINFO and
		SCSICDROM_READ_TRACKINFO. (Not really tested yet.)
		Implementing disk image "overlays" (to allow simple roll-back
		to previous disk state). Adding a 'V' disk flag for this, and
		updating the man page and misc.html.
20070325	Stability fix to cpu_dyntrans.c, when multiple physical pages
		share the same initial table entry. (The ppp == NULL check
		should be physpage_ofs == 0.) Bug found by analysing GXemul
		against a version patched for Godson.
		Fixing a second occurance of the same problem (also in
		cpu_dyntrans.c).
		Fixing a MAJOR physical page leak in cpu_dyntrans.c; pages
		weren't _added_ to the set of translated pages, they _replaced_
		all previous pages. It's amazing that this bug has been able
		to live for this long. (Triggered when emulating >128MB RAM.)
20070326	Removing the GDB debugging stub support; it was too hackish
		and ugly.
20070328	Moving around some native code generation skeleton code.
20070329	The -lm check in the configure script now also checks for sin()
		in addition to sqrt(). (Thanks to Nigel Horne for noticing that
		sqrt was not enough on Fedora Core 6.) (Not verified yet.)
20070330	Fixing an indexing bug in dev_sh4.c, found by using gcc version
		4.3.0 20070323.
20070331	Some more experimentation with native code generation.
20070404	Attempting to fix some more SH4 SCIF interrupt bugs; rewriting
		the SH interrupt assertion/deassertion code somewhat.
20070410	Splitting src/file.c into separate files in src/file/.
		Cleanup: Removing the dummy TS7200, Walnut, PB1000, and
		Meshcube emulation modes, and dev_epcom and dev_au1x00.
		Removing the experimental CHIP8/RCA180x code; it wasn't really
		working much lately, anyway. It was fun while it lasted.
		Also removing the experimental Transputer CPU support.
20070412	Moving the section about how the dynamic translation system
		works from intro.html to a separate translation.html file.
		Minor SH fixes; attempting to get OpenBSD/landisk to run
		without randomly bugging out, but no success yet.
20070413	SH SCI (serial bit interface) should now work together with a
		(new) RS5C313 clock device (for Landisk emulation).
20070414	Moving Redhat/MIPS down from supported to experimental, in
		guestoses.html.
		Preparing for a new release; doing some regression testing etc.
